报告摘要：
The Greater Mara ecosystem in Kenya together with the Serengeti plain in Tanzania hosts the largest and most species diverse migrations of large mammals in the world, including 1.3 million wildebeests, 200,000 zebras and hundreds of thousands of Thomson’s gazelles.
It is also the home for the famous Maasai tribes, which traditionally lived a semi-nomadic pastoralistic life that has been relatively well suited for the wildlife in the area. This situation has changed dramatically with the introduction of private land ownership, sedetarization, coupled with a significant increase in the human population. During the past few years a problem with fencing of private land parcels has started to occur and has lately been reported to having increased strongly. The problem of fencing is that this will hinder the wildlife migrations that are a key function of the ecosystem. I will present the results of a fine-scale mapping of fences in the area based on Landsat satellite imagery from 1985–2016. We can show that even though imagery provides a conservative estimate, some areas within the regions has reached a level where fencing covers > 85% of all available land, and that since 2010 the general picture is that the rate of fencing is increasing dramatically.
