| Leon Slichter walks towards where the native grasses are growing and says that this is a good example of how the Crupina is moving into the bunchgrass. This hillside has a lot of native bunchgrass left on it and it's relatively healthy, hasn't been grazed, although the grazing would probably really stimulate growth and reproduction of seed for othe grass. But what the crupina has done is moved into the bare mineral soil between the bunchgrasses and in time, it will just crowd them out. We see this a lot with all our invading weed species and the native grasses that we have here. The grasses leave exposed soil between the plants so that places where the grasses have sodded up, these native, perennnial grasses are our best defense against the weeds. But, like the bunchgrass, it leaves itself exposed because of the bare spots between each plant.
