A transect is a term in ecology, which is a survey of the natural vegetation through a particular area, between two points, and the species of plants noted at intervals. A Megatransect is a vegetation transect on a large scale, and is a tool used in recent years, to take an ecological census of the natural vegetation and ecosystems of an area.
MegaTransect was the name for a project conducted in Africa in 1999 by J. Michael Fay to spend 455 days on the expedition hike of 2000 km across the Congo Basin of Africa to survey the ecological and environmental status of the region.

A transect is a term in ecology, which is a survey of the natural vegetation through a particular area, between two points, and the species of plants noted at intervals. A Megatransect is a vegetation transect on a large scale, and is a tool used in recent years, to take an ecological census of the natural vegetation and ecosystems of an area.
MegaTransect was the name for a project conducted in Africa in 1999 by J. Michael Fay to spend 455 days on the expedition hike of 2000 km across the Congo Basin of Africa to survey the ecological and environmental status of the region. 'MegaTransect' is named for the transect methodology.
Shortly after the hike, Fay lobbied alongside the President of Gabon to create 13 new national parks, a project that was successful.
In 2002, US Secretary of State Colin Powell and other Bush Administration members gave 53 million dollars to help preserve the Congo Basin.
Mike Fay later went on to carry out the MegaFlyover in 2004.
Also in 2004, an international team conducted a "Megatransect" of the island of Madagascar. Dubbed "Hike Madagascar", the journey covered the entire island. Members met with rural farmers to help them improve their agricultural techniques and discuss their impact on the environment.
History of USA megatransects
One of the first megatransects in the United States, was conducted by Dr. Robert R. Humphrey when he rephotographed 535 miles of the natural vegetation along the United States and Mexico border at the 1890s permanent border monument locations, spaced about five miles apart, and published the work in "90 Years and 535 miles: Vegetation Changes along the Mexican Border" (1987, pub. Univ. of NM Press, 448 pages).
Craig C. Dremann, in 1997, conducted a megatransect surveying over 3,000 miles and at each mile-marker, noting the roadside vegetation, the perennial native grass, and exotic grass status, through the Great Basin ecosystem. The route was from Reno, Nevada eastward to Hot Springs, South Dakota, and from South Dakota, through Wyoming, Idaho, Nevada and returning westward to Bishop, California, and then north to Reno.
In 2005, Dremann conducted another megatransect, this time of the California portion of the Mojave desert, mapping over 1,000 miles on a mile-by-mile basis, for a fast-spreading exotic mustard species, Brassica tournefortii, noting the locations and density of the Mojave desert Mustard infestation in California.
In 2007-2008 J. Michael Fay and Lindsey Holm completed a 1300 mile of 333 days. This was a transect that spanned from the southernmost to the northernmost redwood tree in California and Oregon. They walked extensively on private timberland and public land recording data on historical exploitation, current forest stand characteristics, silviculture and many other aspects of the redwood ecosystem. The results will be published in National Geographic in 2009.
MegaTransect future
For a rapidly-changing planet, megatransects establish baseline data from which to draw future trends, and they can focus attention on particular ecosystems which are disappearing faster than others.
Establishing standard megatransects on specific regions or throught various ecosystems of each continent, and periodic re–measurement of the ecological conditions along routes, every five to ten years, would provide very valuable measured data on environmental trends.
