Abstract
In the preceding paper [21], we have introduced a tree-grass competition
model for describing the kinematics of forest-grassland system and have found that the
model admits some solutions showing coexistence of forest and grassland. The purpose
of the present paper is then to investigate the boundary curves which partition forest
patches and grassland patches. Through the investigations, we want to clarify the
properties of segregation patterns of tree-grass coexistence in terms of forest connectivity. As it is very difficult to handle the very model equations in [21], we will make
a reduction of the full model by extremely restricting the range where the parameters
of equations can vary.
