Interested in DIY adventure travel, exploring, and organising your own expedition?

This is a request for like-minded people (ten or so), from any nationality, to come together to organise their own expedition to that remote destination you always wanted to explore, but never got around to.

It may be that you lack the confidence to go it alone, or the logistics and cost has been prohibitive. What I am proposing here is that you come forward to discuss where you want to go and what you wish to do when you get there. If we can get enough like-minded people together, who want to go there then we can pool our resources and organise that expedition much easier and cheaper than if you were to try and do it on your own.

The destinations I am referring to are generally those that may be extremely remote like Madagascar, Borneo, Papua New Guinea, Sumatra, Peru, Chile, Brazil, Colombia, Bolivia etc.. Or less remote, but nevertheless difficult for one to organise on ones own like China, Vietnam, Mexico, or even Africa and Australia. I’m not suggesting you do anything touristy like visit cities and temples, although these things are usually unavoidable.

Like-minded people are those with an interest in the natural world. You may be an academic botanist or zoologist needing to study a particular species, a geologist interested in a mountain range or formation. But you could also be a complete novice with an interest in ornithology, or you just want to see a wild tiger before they go extinct. Whatever your background, if you want to do something really special and adventurous in your lifetime you can, by pooling together with like-minded people to undertake an expedition or field trip everyone gains in the shared knowledge of the participants, the security of travelling together, and the reduced logistical costs.

I envision these field trips and expeditions to be of the duration of a few weeks to a couple of months. Longer trips are not out of the question, but I can tell you from my own experience that expeditions lasting longer than a month become tedious, tiring, and generally much more difficult. Besides, many people can’t spare the time, and people invariably become irritating when you travel for too long with them.

And to give you an idea of what to expect, it is more often the case that most of the time is spent in hotels where we make excursions out into the field. Sometimes we work out of a base camp, other excursions might entail a 5 day trek through a rain forest where we hold up each night in hammocks. Some countries insist that we employ at least one guide to travel with us especially if we have a collecting permit. In most cases it is preferable to have a motor vehicle, mini bus, truck, car or boat, to give us the freedom to get us and our kit close to where we need to go, it then works as our base camp. The itinerary is decided by the species we set out to see, and the minimal amount of effort needed to get in, see that or those species and get out.

About me
I’m not the kind of person who likes to ‘blow my own trumpet’ and talk much about myself, however, I understand that in the context of this you do need to know quite a lot about me.

My name is Phil, I am male, 48 years old, married with two teenage boys, British, based in Cornwall, Southwest UK. And I own Trebrown nurseries and this website. My academic background is in biology and geology, but I specialise in botany and palaeobotany, mainly [Arecaceae] palm trees, [Cycadae] cycads, [Musaceae] bananas, [Pteridophyta] ferns, and conifers especially Araucariaceae and Podocarpaceae. My interests extend further than this though and I am fascinated by everything in the natural world, including birds, mammals, invertebrates, reptiles and fish.

I maintain a high level of fitness, but would not go so far as to say I am fanatical about it, I generally eat healthily, but can, on occasion eat junk, and I have been known to consume large levels of alcohol (never out of context). I’m a keen cricketer and play throughout the year. I run and work-out regularly. When I was younger I was keen on hang-gliding, climbing and kayaking, but these days my only adventure sports include scuba diving and hiking, with the occasional bit of tree climbing.

I have received military wilderness survival training and logistical training in planning and moving large volumes of equipment, kit, and personnel, in and out of combat zones. I’ve been trained in first aid (certificate now expired). I am fluent in conversational Mandarin Chinese, and I speak basic Indonesian/Basa Malay. I hold an open-water scuba diving licence.

I also hold a driving licence to drive any motor vehicle with the exception of high capacity seating PCVs (busses), though I’m licensed to drive 16 seaters, HGVs of all classes, automobiles, motorcycles, and have been highly trained to operate vehicles in all terrains – off road in remote locations. Also to maintain and fix vehicles on location.

I have travelled through approximately 67 countries, and driven vehicles through 28 of those countries. Although I have partaken in expeditions all over the world, mainly botanical expeditions, I was based in Taiwan for 10 years and most of my work has been throughout Southeast Asia – China, Taiwan, Tibet, Japan, Philippines, Indonesia, Malaysia, Nepal, India, Pakistan etc.. I also lived in Australia for 2 years, and travelled extensively there and New Zealand. Over the last few years, due to my knowledge of the countries and my language skills, I have assisted, and led many academics into Asian destinations for them to study their specific subject in the field.

Lastly, I have been fortunate over the years to have seen, in the wild, many of the world’s rarest and most fascinating animals, birds, and plants. But you can also see these if you want to.

Now about you
Contact me using the secure link provided. The information you submit will not be published in any way, neither will the information be transmitted to other interested parties without your express permission. I will post your basic destination idea on this page to see if there is public interest.

Start by suggesting a destination, and what it is (if any) that you would like to see or study while you are there. It may be that you don’t mind where you go and are happy to join the party wherever we go.

Provide a little background about yourself, and include information about your fitness. Don’t worry if you have a disability or think you’re not fit enough, contact me anyway and we’ll discuss it. Your fitness will improve tremendously both during preparation and during the expedition. But do remember that you could put other expedition members at risk if you don’t disclose a serious medical problem beforehand.

If you have specialist knowledge about the country, environment, species, language, whatever, Let me know. Likewise, if you have the most experience travelling in the country you will be the expedition leader (help provided). Otherwise, I will assume expedition leadership.

If motor vehicles are to be needed, then I will take on that responsibility, but quite often more than one driver is needed. So if you feel you have the ability to drive and or maintain a vehicle then you should also advise me so.

Even if you can’t do this trip this year, but would like to do it before you die, contact me right now regardless, we can discuss it by email or phone, and it might be more feasible than you originally thought. Please don’t be put off suggesting a destination because it has no palm trees and you think I won’t want to go there, I’m interested to go to any destination regardless of whether I’ve been there before or not.

Contact link, opens a contact form in a new window. Or leave a reply at the bottom of the page.

One last thing. I want to make this ‘Not for profit’. I have to travel all the time anyway, I see this as a means to reduce my costs, and meet interesting people and learn from them. I may have to charge some sort of administration fee if its taking a lot of my time and resources, but the over-all objective here is to reduce the expedition costs for all participants.

Look forward to hearing from you.

Speak to you soon,

Phil Markey

Suggestions:

Two weeks travelling down the eastern side of Taiwan, and a trip over to Lanyu island in the summer 2013.
This is a suggestion from myself. Fairly simple in the planning – travelling in a minibus and staying in hotels every other day or so. Other nights spent outdoors in hammocks, to save hotel costs, and to get into the wilderness. Wildlife includes butterflies, birds including eagles and the Lanyu Scops owl, snakes, and a lot of plants – ferns, bananas, and palms including 3 calamus (ratan) species, Arenga engleri, Pinanga tashiroi, Phoenix loureiroi, and Livistona chinensis var. subglobosa. I know the habitats like the back of my hand, and I speak Chinese.

An addition to this could be Two weeks in the Japanese Ryukyu islands to see: ferns, spectacular environments, Cycas revoluta, and palms including Arenga ryukyuensis, Satakentia liukiuensis, and the most northerly population of Nypa fruticans.
Contact me or leave a message if you’re interested.

The Natural Distribution of Livistona chinensis Past and Present

Including Livistona chinensis var. subglobosa and Livistona chinensis var. boninensis

There are three natural forms of Livistona chinensis formally known as Livistona chinensis (Jacq.) R.Br. ex Mart., Hist. Nat. Palm. 3: 240 (1838). from the Chinese mainland, Livistona chinensis var. subglobosa (Hassk.) Becc., Webbia 5: 16 (1920). from the Ryukyu archipelago of Japan & Taiwan, and Livistona chinensis var. boninensis Becc., Webbia 5: 12 (1921). from the Bonin Islands of Japan. However, these names have recently been taxonomically revised where Livistona chinensis var. subglobosa has been reduced to the species level as Livistona chinensis (Jacq.) R.Br. ex Mart., Hist. Nat. Palm. 3: 240 (1838). and Livistona chinensis var. boninensis is now Livistona boninensis (Becc.) Nakai, J. Jap. Bot. 11: 222 (1935).

Livistona chinensis var. subglobosa

Livistona chinensis var. subglobosa

Livistona chinensis var. subglobosa is perhaps justifiably not deserved of subspecies status, as the morphological differences are slight when compared with the Chinese mainland form. The main noticeable difference is to be seen in the size and shape of the seeds. The mainland China form, which is the commonest form in cultivation around the world produces a typically elongate, smaller seed (15 – 9 mm) than the Japan/Taiwan form which produces a larger, more globose seed (18 – 12 mm).

Livistona boninensis has had a much longer natural isolation, and differs in the height of the trunk being 18 m or more tall compared to 12 m for L. chinensis. Livistona boninensis‘ seeds are also larger but seldom ever as globose as L. chinensis var. subglobosa.

As I mentioned the mainland China form is by far the commonest form in cultivation with the main sources of seed being India, Pakistan, the USA and Europe. Livistona chinensis var. subglobosa from Taiwan and Japan is quite uncommon in cultivation outside of Taiwan and Japan, but is by far the most widespread and commonest form in the wild today. The former name of L. chinensis var. subglobosa was most useful as the indicator of provenance of the two main forms, and therefore identifying it as the Japan/Taiwan form and the most cold-hardy of the two (Zone 8b) (-6.7 to – 9.4). L. boninensis is equally as hardy.

Natural distribution of Livistona chinensis today

Livistona boninensis a palm native to Ogasawara-shoto or Bonin Islands (typical oceanic islands, located 1,000 km south of Tokyo, Japan), is endemic to several of the islands and introduced to the nearby Iwo (or Volcano) Islands. The Bonin Islands is a scattered archipelago of 20 or more rugged volcanic islands with many additional islets and rocks. The archipelago extends from the island of Mukojima in the north to the Iwo Islands in the south. The Bonins can be divided into three main clusters of islands: the Mukojima, Chichijima, and Hahajima-rettos groups. The native range of L. boninensis today is the Hahajima-retto group.
bonin-islands

The climate of the islands is subtropical, with a marked seasonal temperature variation, ranging from a sea level mean of 18°C in February to 25°C in July and August. A regular dry season occurs from January through March; sometimes there is also a secondary dry season in July and August.

The basal rocks of the Bonins were formed during the Tertiary 65 to 1.8 million years ago by submarine volcanic activity. Boninite, an andesitic volcanic rock rich in magnesium oxide, chromium, and silicon dioxide, is widespread, and is overlain in some areas by volcanic breccia. Most of the islands drop sharply to the ocean, with sea cliffs ranging from 50 to 100 meters in height.

The primary subtropical broad-leaved evergreen forest that remains on the islands can be classified into 3 major types. The palms occupy a dry forest on rocky slopes where the palm is a second dominant and is associated with Pandanus boninensis and Ochrosia nakaiana.

Livistona chinensis on the mainland of China no-longer has any truly natural wild stands of trees in any number. Small populations can still be found around Guangdong and on the island of Hainan. Although naturalised populations of the palm can be found in other areas of China and other South-East Asian countries, as well as some South Asian countries and Hawaii. The palm is commonly planted as a street ornamental throughout warm-temperate regions of the world.

Livistona chinensis var. subglobosa is naturally distributed from Taiwan through the islands of Okinawa and as far north as Kyushu, Japan, where it grows along shores washed by the warm Kuroshio current. However, due to it’s lowland habitat no wild populations exist in Taiwan today. In Japan, so called virgin L. chinensis forest is now found only on the islets of Aoshima and Tsukishima in the Miyazaki prefecture, Kyushu, Japan. The islet of the gods on Aoshima is the extreme northern limit of the species, and this is also officially recognised as the largest single population of the species in Japan consisting of 4000 individuals.

However, I report here, for the first time that by far the largest virgin population of Livistona chinensis var. subglobosa is to be found on a tiny island called Uotsurijima (Japanese) or Diaoyudao (Chinese). This is the largest island of the Senkaku Islands (钓鱼岛及其附属岛屿) or what we know as the Pinnacle Islands. Uotsurijima or Diaoyudao Island located at 25°44’39”N 123°28’26”E has an area of 4.3 square kilometres (1.7 sq mi) and a highest elevation of 383 metres (1,260 ft). L. chinensis is the dominant tree species on this island and I estimate this population to be over 100,000 individuals.

The Pinnacle Islands are a group of disputed, uninhabited islands currently controlled by Japan, but also claimed by both the Republic of China on Taiwan and the People’s Republic of China as part of Taiwan Province. The island group is made up of five small non-volcanic islands which sit on the edge of the continental shelf of mainland China, and are geologically separated from the Ryukyu Islands by the Okinawa Trough. Japan argues that these islets are part of the Ryukyu Islands. They are 170 kilometers (106 mi) north of Ishigaki Island, Japan; 186 km (116 mi) northeast of Keelung, Taiwan; and 410 km (255 mi) west of Okinawa Island.

The dispute appears to date from the 1968 announcement by two Japanese scientists that there may be large reservoirs of oil under the continental shelf below the islands. From the end of World War II until 1972, the United States occupied Okinawa, and controlled the islands, whose ownership was undisputed until 1970, when both China and Taiwan began to claim that the disputed islands were given to Japan in the Treaty of Shimonoseki in 1895 and should therefore be returned to Taiwan (after the end of World War II in 1945, all “unequal treaties” forced on China were declared void, including the Treaty of Shimonoseki, concluded in 1895). In 1971, the US expressed its intention to hand over the occupied territories, including the disputed islands, to Japan. Both the China and Taiwan governments protested and reiterated their claim to sovereignty over the islands. Taiwan made the official announcement on 11 June 1971, followed by China on 30 December. However, the United States handed over the disputed islands to Japan in 1972, even though they have not taken a definitive position on the sovereignty of the territory, considering the islands an “administrative territory” of Japan.

After losing the First Sino-Japanese War, Qing China signed the Treaty of Shimonoseki on 17 April 1895. This Unequal Treaty ceded Taiwan, Okinawa and its surrounding islands to Japan. The Chinese governments see the disputed islands as having been included in the islands ceded to Japan by the treaty, even though the Treaty did not explicitly enumerate all the islands ceded under it. On this basis, they argue for Chinese sovereignty over the islands for two reasons. First, that all the Unequal Treaties are null and void and thus the islands are still part of Taiwan Province of China. Secondly, that since the disputed islands were ceded along with Taiwan in 1895, therefore when Japan returned to China all territories it had obtained from China since the First Sino-Japanese War at the end of World War II, the disputed islands were returned along with Taiwan to China.

The first frustrating issue regarding this dispute is that no scientist can get anywhere near the island to evaluate the palm population or any of the other flora & forna. The Senkaku mole (Nesoscaptor uchidai) is an endemic mammal to the island and could, for all we know be extinct now. The second frustrating issue is regarding the feral goat population on the island, which is totally out of control. A sum total of 3 domestic goats were deliberately introduced to the island in 1978. There is now an estimated 300+ animals devastating the juvenile palm population, and due to the dispute over the island no government is prepared to send in hunters to eradicate the goats.

Natural distribution of Livistona chinensis in the past

The historical distribution of Livistona chinensis was certainly much more widespread than it is today. It is known to have occurred on Tsushima island (at latitude 34°N) located to the south of the Korean Peninsula. Evidence also points to the species being much more numerous on all the islands it occurs on today.

When haplotypes from the amplified DNA band patterns of the Japanese distribution of the species were compared by Japanese scientists they concluded the true origin of the species points to northern Taiwan, Iriomotejima, Ishigakijima and Okinawa in Japan. These same scientists also supported the hypothesis that natural distribution throughout its range in the islands occurred through oceanic drift of seeds on the Kuroshio current. I totally disregard this hypothesis based on the facts that viable seeds do not float even on salt-water, and that salt-water quickly kills the developing embryo within the seed.

Therefore, we need to look for lower sea-levels during the ice ages to see how distribution of this palm occurred. The current interglacial that we are currently enjoying started about 12,000 – 10,000 years ago when the planet warmed and the ice-caps started to melt making the sea-level rise. That last glaciation lasted roughly 100,000 years, where the Glacial Maximum occurred about 20,000 – 18,000 years ago, and it was at this time that the sea level was at its lowest, roughly 120-150 m lower than it is today.

China - Japan sea-levels during last Glacial Maximum

China - Japan sea-levels during last Glacial Maximum

As you can see from the map the lower sea-level explains how Livistona chinensis extended from Taiwan to Japan and Korea in the north, and to Hainan China in the south. However, this does not explain how the palm spread throughout the islands of the Ryukyu Archipelago of Japan. Nor does it explain how Livistona boninensis reached the Bonin Islands of Japan. For the palm to be able to reach, and spread through the Ryukyu from Taiwan the sea-level would have needed to be at least 400 m lower than today. To reach the Bonin Islands would have required a sea-level at least 1500 m lower than today. If we go back even further in time to evaluate even earlier Ice Ages then the Ice Age preceding the last occurred about 145 million years ago between the Jurassic and Cretaceous. But this Ice Age was not as cold, and did not produce very low sea-levels. Besides, we have not been able to find any palm relatives in the fossil record which date older than about 115 – 120 million years.

We have already mentioned that the Bonin Islands were formed during the Tertiary 65 to 1.8 million years ago by submarine volcanic activity. This same is true for the entire Philippine Arc of volcanic islands, which includes the Batan Islands of the Philippines and the Ryukyu Archipelago. The island of Taiwan is even younger and was formed less than 6.5 million years ago by the Luzon Volcanic Arc crashing into the Chinese continental margin and in doing so forced the land mass of Taiwan up from the sea bed.

The Pacific Rim, of which the Ryukyu is part was much hotter and far more active in the past, and during the last 1.8 million years has been rapidly cooling. With this the Ryukyu Archipelago and the Bonin Islands of Ogasawara-shoto have been sinking in a process called Ridge Subduction. Newly created, hot rocks are buoyant on the mantle, and therefore rise, displacing the seawater above it. Thus making shallow seas. As the rocks cool over time they sink further into the mantle. Making deep water above them. The full extent of the elevation they once were and the amount they have sunk is too difficult to quantify. But 1000 – 2000 m is not impossible, and this could be the answer we are looking for. Failing this the only explanation could be that seeds have been carried there by humans or birds, or that the seeds got there by floating on oceanic debris.

Conclusion: Livistona chinensis possibly occurred in the northern Taiwan area around 1.8 to 20 mya., but could have arrived there as late as 20,000 – 90,000 years ago. The species reached its maximum around 20,000 years ago when the sea-levels were 120 m lower than they are today. During this time its distribution stretched from southern China to Korea and as far north-east as Tokyo Japan. We assume that the islands of Ogasawara-shoto and Ryukyu Archipelago were much higher than they are today, and that 20,000 years ago they were still high enough to form a land bridge. Livistona boninensis became isolated at a very early stage, and Livistona chinensis has been slowly declining in numbers in recent times.
