In March 2005, I visited the Amazon rain forest in Ecuador. I flew into Coca via Quito. From Coca I took a boat to the La Selva Jungle Lodge, about 40 km (25 miles) downriver. I stayed at the lodge for 5 days. After a boat trip back to Coca, I boarded the Manatee and stayed on that boat for 5 days, cruising up and down the Rio Napo.

The transportation medium of choice in this area is of course the boat. There are not many roads in the jungle. The normal boats are somewhat slow. The lodge has much faster boats. The fastest boats are the speedboats of the oil companies. They are REALLY fast.

The La Selva Lodge was excellent, I can really recommend it. The staff is knowledgeable and helpful. The organization is very conscious of environmental issues. It is a North American organization, but the lodge employs mainly local people. The lodge can only be reached by foot and canoe. All luggage is transported by porters from the Rio Napo to Garzacocha Lake (Heron Lake, an apt name), on which the lodge is located. It is about a 15 min walk. From there everything (and everybody) continues in canoes. One of the pictures below shows the supply ship with a load of soda and beer  ;-) The canoe ride takes another 20 min. It is very scenic, especially during sunset. There are no motor conveyances whatsoever in and around the lodge, everything moves by people power.

I was somewhat concerned about mosquitoes in the lodge, but found out soon that this is not an issue. There are two types of water in the Amazon basin, white water and black water (see picture below). The white water is river water that comes from the mountains. It is light colored from the sediment that the river carries. It makes the river water completely opaque. The black water is water in the lakes and brooks in the basin. It is black from tannin from decaying vegetation. It is black but transparent. This water is very acidic. Mosquito larvae cannot live in acidic water, so there are no mosquitoes around the black water. Since the lodge is on a black water lake, there was no problem with mosquitoes. The river with white water, is a completely different story. The mosquitoes like that water, so the islands in the river, that have lots of standing water, are swarming with mosquitoes. That was a problem during the excursions from the Manatee. It was especially severe during one excursion on a large island in the Rio Napo. On the Manatee itself, it was not a problem, since you are two decks up, and mosquitoes don't fly much about ground level. The ship was also on running water, so mosquitoes don't hang around much.

The food was very good. Meals are included in the price, only the bar bill is extra. The local beer is pretty good, and in ample supply.

The excursions are interesting. The excursions around the lodge are either by paddle canoe or on foot. To the excursions to the parrot clay licks you go to the Rio Napo by canoe and by foot, and then take a short motorboat ride on the river. Behind the lodge is a 35 m (115 ft) high canopy observation platform, build around a tall tree. It gives you a splendid view over the jungle canopy.

The second part of the trip was on the Manatee. There were only two other tourists on the ship while I was there. The accommodations were very comfortable, there even was air-conditioning in the cabin. The food was excellent, and the crew friendly and knowledgeable. We usually did all-day excursions from the ship with a motor boat. We went to Limoncocha, where we saw the caimans, and to Pañacocha (Piranha Lake), where we saw a lot of birds.

The main attractions in the jungle are the plants, and of course birds, insects, and monkeys. We didn't see any larger mammals. The variety of plants is what you would expect from a rain forest: it is huge. The number of insects and the number of birds species is equally impressive. As far as mammals are concerned, we saw mainly monkeys.

The plant variety is enormous. Some of the trees where huge. They have very varied types of bark. One of the trees had a neat means of getting rid of the lianas and other plants growing on them: It completely sheds its bark every year. This gets rid of anything that tries to hold onto it. The lianas are everywhere. They sometimes have really interesting cork screw-like shapes. The strangler fig is the most notorious. It grows around a tree and eventually chokes it to death. By that time the strangler fig has become so strong that it can stand on its own. There where lots of epiphytes, plants that grow on other plants, like the philodendrons and bromeliads.

Most of the forest along the main river is secondary growth. This means that the original rainforest had been cut down. The secondary growth doesn't have the large trees, and is much denser with small underbrush. The fertile soil in the Amazon basin is usually only a very thing layer. Underneath it is non-fertile sand. When the rainforest is cut down, and the land is farmed, the nutrients in that thin layer are used up very quickly, and the land becomes unusable. It then takes a long time for the rain forest to come back, if it ever can. Clear cutting and loss of fertile soil are the biggest danger for the rain forest.

Insects are everywhere. They are in the lodge as well. Some of the tour guests were disconcerted by them, but they didn't bother me. I didn't see any in my room (mainly because I wasn't really looking for them). I think that is the best way to handle them, just don't look at them. It may be ostrich policy, but I think it works for my relationship with insects  :-)

One particular type is ever present: Ants. There are army ants (they are roving ant colonies without a permanent nest), bullet ants (they are almost 3 cm (1.2") long, with a very painful bite), and leafcutter ants (see pictures below). The leafcutter ants bring pieces of leafs to their underground nests. They then grow a special fungus on these leafs. The fungus is their food.

Other ubiquitous insects are grasshoppers and crickets. They look somewhat similar. The grasshoppers have the short antennae, the crickets have long ones. Some of them were colorful, others were camouflaged.

Then there are beetles, lots of different species. There are many more beetle species on earth than species of any other kind of animal. British biologist J. B. S. Haldane was once asked by theologians what conclusions he could draw about God from years spent studying life on Earth. Haldane is reported to have said that God must have "an inordinate fondness for beetles."

Spiders also are ubiquitous. From small ones all the way to the big tarantulas. Some of them build large webs, others hunt on the ground. A strange looking one was the scorpion spider.

Wasps are also very common in the jungle. The most amazing ones were so-called "Marching Wasps". We were on a boat, canoing along one of the small brooks when our guide stopped. He said we should yell real loud "March" on a count of three. One, two, three, "MARCH". At that moment there came a loud noise from the tree above us. It sounded just like a marching army. Our guide explained that it is a warning mechanism of the "Marching Wasps". When they hear a threatening noise, they start to beat their wings inn unison in the nest as a warning to whoever is around. It was a fantastic experience to hear that.

As for mammals, we saw mostly monkeys and bats. The bats were very interesting, we got pretty close to a bunch of them that were roosting on a dead tree trunk through the day. We saw monkeys quite frequently, but not from very close, so I don't have any really good pictures of monkeys.

The black water lakes have plenty of fish, including piranhas. Some of the people in our group were fishing for piranhas and they caught quite a few of them. One of the lakes, Limoncocha, has quite a few caimans in it. We did see them just after sunset on an evening canoe ride. They are easy to spot. You shine a search light across the lake, their eyes, reflecting the light, look like bright flashlights.

I did see some lizards and frogs, but not all that many. They seem to be well camouflaged.

I had a great time and saw a lot of wildlife. The two parts (jungle lodge and ship cruise) are somewhat redundant, since you visit some of the places twice (e.g. the parrot clay licks). But it still was worth it I think. The best way to do that would probably be a cruise that goes longer distances than the Manatee.

If you know the name of any of the plants or animals for which I don't have a name, I would appreciate it if you would send me that name to email me
