module 6 populations and sustainability Flashcards
interspecific competition
competition between different species
intraspecific competiton
competition between members of the same species
conservation
maintain of biodiversity through human action
preservation
protection of an area by restricting human interference
outline methods of sustainable timber production
coppicing
tree trunks are cut close to the ground
so new shoots can grow from cut surface
eventually, the new shoots are cut
known as rotational coppicing
how can large-scale timber production be more sustainable
selective cutting of only the biggest trees
replant trees after they are cut
manage pests and pathogens
protect areas for indigenous people

use of nets with different mesh sizes
protecting breeding seasons
introduction of fish farming

conservation of lowland bogs
filling ditches to allow water to pool on top of the bog surface
