results from deforestation. It refers to the splitting of a large
habitat into two or more smaller habitats with no way for the
animals to travel between the forested lands. For example, a
particular section of a vast forest may be cut down to make way for
a city. The forest may then be spilt into two chunks by the city
and, as a consequence, the species found within the forest are also
cut off from one another -- unable to interact and interbreed.
A solution to this
problem is to leave a corridor, or strip of trees, between the two
fragments to allow the animals to travel between the two forests.
This solution has become employed in many countries in recent years,
including Costa Rica.
