Popis: | Netleaf hackberry (Celtis reticulata) is a deciduous shrub native to the southwestern United States and northern Mexico. Previous field observations have shown limited numbers of juvenile hackberries in the wild. This could be due to low germination and survival rates, but field germination trials have not been done. In the foothills of the Wasatch Mountains in Utah, hackberry shrubs have been shown to grow in association with boulders, likely using them as nurse objects. This experimental study field-tested germination and survival rates around boulders in this area. We located 26 boulders and planted 25 hackberry seeds on the north, west, south, and east sides of each boulder (n = 2600 seeds). In the following year, we counted the number of hackberry seeds that had germinated and become established near each of the boulders' sides. Overall, germination rates were extremely low, with only 55 (2.1%) of the planted seeds germinating and only 19 (0.7%) persisting until the end of the growing seaso... |
