Organic Analysis for Conservation in Peruvian Amazonia


For many guests to Peru’s Amazon area, the pleasure of encountering wildlife – and native inhabitants – within the firm of a naturalist-guide is ample. However for these of a scientific bent, there may be the chance to get hands-on with some conservation-oriented analysis, throughout a keep on the Rio Amazonas Analysis Station.

Rio Amazonas Research Station - Biological Conservation - Students Taking Notes in Amazon Rain Forest

Notice taking in Amazon rainforest.

Not solely is that this a good way to understand the wonders of the rainforest and find out about biodiversity, tropical ecology, and the indigenous peoples of Amazonia, however the subject research you participate in might be used to supply the scientific base for wildlife and community-based conservation; the impression of local weather change and the wildlife commerce on the area; and the restoration of endangered species.

It’s hoped that – at the side of worldwide universities and establishments akin to WWF, the G & B Moore Basis, WCS, USAID, The Darwin Initiative, FondAm and CIFOR – the outcomes will advance community-based wildlife administration, protected space administration, wildlife conservation coverage within the Peruvian Amazon, and result in the creation of recent protected areas.


Rio Amazonas Research Station - Biological Conservation - Floating Lodge

Rio Amazonas – historic riverboat.

The historic Rio Amazonas riverboat serves as a splendid floating lodge, from which to discover the Yarapa River basin.

Located between the Pacaya-Samiria Nationwide Reserve and the Tamshiyacu-Tahuayo Neighborhood Reserve, in one of many largest protected space complexes in Peru, the Yarapa web site is a flooded forest ecosystem of ample wilderness and a number of the biggest variety of animals and vegetation on Earth.

Aquatic and terrestrial wildlife consists of: wholesome dolphin and primate densities; ample wading birds and fish; recovering otter and caiman populations; together with quite a few different mammals and birds.

The native inhabitants are concerned with the conservation actions and play a significant position in serving to to preserve these rainforests.


While staying on the Analysis Station, guests might be concerned with analysis on monitoring wildlife populations.

Dr. Bodmer in unguarded second.

Surveys embrace ungulates (hoofed mammals akin to deer, tapirs and peccaries), macaws, large-bodied primates, caimans, dolphins, large river otters, manatees, river turtles, sport birds, understory birds, giant cats, different giant mammals, palm bushes and enormous fish.

Beneath are examples of the format this analysis may take … all within the firm of certified biologists and native subject assistants, led by Professor Richard Bodmer, a number one authority on the Amazon within the province of Loreto.


Terrestrial mammals (ungulates and rodents), arboreal mammals (eg primates) and sport birds are surveyed utilizing transects. Trails a mean of three km (2miles) lengthy are walked at roughly 1 km/hour from 7am to noon and a pair of to 4 pm.

When a bunch of animals is encountered, the variety of people is recorded, and the perpendicular distance from the path to the primary particular person sighted is measured. Inhabitants densities are calculated as variety of people per sq. kilometre (ind/km2).

Terrestrial mammals are additionally surveyed with infrared and movement digicam traps. Cameras are arrange over areas of roughly 100 sq. km (39 sq. miles), throughout habitat varieties. They want common checking, to find out battery ranges and common functioning of the items.


Rio Amazonas Research Station - Biological Conservation - Spotting Macaws

Looking riverbank for macaws.

Macaws, parrots and parakeets are surveyed by counting the quantity that cross designated spots alongside the shoreline of rivers, lakes, and channels in a 15-minute interval. Censuses are achieved from 5.30 to 9.00 am and 4.00 to six.30pm when motion is normally unidirectional … from roosting to feeding websites, or vice versa.

Species are decided by visible and auditory identification, and data are taken of the variety of people in a flock and the minute they’re noticed.


Weighing & measuring fish as a part of survey.

Fish are surveyed utilizing gill nets which are 30 m (98 ft) lengthy, 3 m (10 ft) deep, and with a mesh measurement of three.5 inches (7.6 cm). These are set for one hour in rivers, lakes, channels, and flooded forest habitats with weak currents.

These fish which are caught on this time are categorised in response to species, weight, commonplace size, and the geographic location, earlier than being launched again into the water.

A side-scan sonar can also be used to find out the abundance of fish in designated shallow areas. The sonar is connected to a slow-moving skiff: fish replicate white on the sonar because of oxygen held in intestines, swim bladders and gills.

The identical sonar may also be used to file dolphins.


Waterfowl are surveyed by shoreline transects within the early morning (5.30 – 9 am) and late afternoon (4 – 6.30pm).

Utilizing an aluminium skiff, surveyors journey slowly (2 km/hr) alongside 5 km (3 miles) of river, lake, and channel habitats, recording all perched or flying waterfowl which are seen.

Inhabitants abundance of every species is calculated as variety of people per km (ind/km).


Amazon River Dolphin in Yarapa River.

An identical course of is used to survey dolphins, though the hours are completely different: 7am – noon and a pair of – 4pm.

Dolphins are recorded visually when breaching the water floor, and the variety of dolphins, pod measurement, and habits are decided by visible monitoring.


Caiman being measured throughout nighttime survey.

Caiman surveys are performed after darkish: 8pm – midnight.

Once more, utilizing a skiff travelling alongside a 5 km (3 mile) transect, caimans are situated by their eye reflections utilizing a highlight and approached to a distance the place observations could be made.


Rio Amazonas Research Station - Biological Conservation - Terrestrial Amphibian Counting

Terrestrial amphibian encountered throughout survey.

Amphibians, by nature of being each aquatic and terrestrial, require two strategies to survey.

Aquatic surveys are performed after darkish by rigorously driving a skiff into floating vegetation. All frogs sighted or captured inside a 2 m (6.5 ft) radius of the boat are recorded. The info consists of species, intercourse, weight, measurement, microhabitat sort, habitat temperature, and humidity.

To survey terrestrial amphibians, transects of 500 m (1/3 of a mile) within the forest are achieved throughout each day and nighttime. Frogs sighted or captured are recorded, together with the perpendicular distance from the transect.

All frogs are launched in the identical location as they have been captured.


Fishing bat being inspected (then launched).

Fishing bats are surveyed at night time utilizing 5 km (3 miles) aquatic transects utilizing an aluminium skiff travelling at 10 km (6 miles) per hour. Bats are counted utilizing a sonar bat field and spot gentle.

Forest bat species are recorded utilizing multi frequency sonar recording tools.
