1. Rodent damage to natural and replanted mountain forest regenerationMarta Heroldová, Josef Bryja, Eva Jánová, Josef Suchomel, Miloslav Homolka, 2012, original scientific article Abstract: Impact of small rodents on mountain forest regeneration was studied in National Nature Reserve in the Beskydy Mountains (Czech Republic). A considerable amount of bark damage was found on young trees (20%) in spring after the peak abundance of field voles (Microtus agrestis) in combination with long winter with heavy snowfall. In contrast, little damage to young trees was noted under high densities of bank voles (Myodes glareolus) with a lower snow cover the following winter. The bark of deciduous trees was more attractive to voles (22% damaged) than conifers (8%). Young trees growing in open and grassy localities suffered more damage from voles than those under canopy of forest stands (X2=44.04, P < 0.001). Natural regeneration in Nature Reserve was less damaged compared to planted trees (X2=55.89, P < 0.001). The main factors influencing the impact of rodent species on tree regeneration were open, grassy habitat conditions, higher abundance of vole species, tree species preferences- and snow-cover condition. Under these conditions, the impact of rodents on forest regeneration can be predicted. Foresters should prefer natural regeneration to the artificial plantings Keywords: forest regeneration, mountain forest, small rodents, Czech Republic Published in RUP: 15.10.2013; Views: 2729; Downloads: 83 Link to full text |
