Forest Pest Management
Subsoiling is becoming a standard practice to alleviate detrimental soil compaction following biomass harvesting in eastside pine and mixed conifer forests in California. Compaction of soil following the harvesting can be detrimental to growth of residuals, to establishment of natural regeneration, and may change long term soil productivity. The short and long term effects of this subsoiling pr...
متن کاملFOREST PEST BIOLOGICAL CONTROL PROGRAM IN HAWAI't
Forest weeds were not considered to be a major management problem in Hawai'i until the latter quarter of the last century. Most previous biological control programs in the state were against agricultural pests. An interagency committee (U.S.D.A. Forest Service, National Park Service, Hawai'i Department of Agriculture, Hawai'i Division of Forestry and Wildlife, and the University of Hawai'i) was...
متن کاملMarket Adaptive Control Function Optimization in Continuous Cover Forest Management
Economically optimal management of a continuous cover forest is considered here. Initially, there is a large number of trees of different sizes and the forest may contain several species. We want to optimize the harvest decisions over time, using continuous cover forestry, which is denoted by CCF. We maximize our objective function, the expected present value, with consideration of stochastic p...
متن کاملReduced biological control and enhanced chemical pest management in the evolution of fungus farming in ants.
To combat disease, most fungus-growing ants (Attini) use antibiotics from mutualistic bacteria (Pseudonocardia) that are cultured on the ants' exoskeletons and chemical cocktails from exocrine glands, especially the metapleural glands (MG). Previous work has hypothesized that (i) Pseudonocardia antibiotics are narrow-spectrum and control a fungus (Escovopsis) that parasitizes the ants' fungal s...
متن کاملForest bolsters bird abundance, pest control and coffee yield.
Efforts to maximise crop yields are fuelling agricultural intensification, exacerbating the biodiversity crisis. Low-intensity agricultural practices, however, may not sacrifice yields if they support biodiversity-driven ecosystem services. We quantified the value native predators provide to farmers by consuming coffee's most damaging insect pest, the coffee berry borer beetle (Hypothenemus ham...
