Instrumental Values to Humans
Temperate deciduous forests have many uses for humans including: wood for
building, land for agriculture and stone for mining (once trees are eliminated),
places to live, and animals to hunt.
Mining in Germany where there was once a deciduous forest
Threats to Deciduous Forest Biomes
Industrial air pollutants Acid rain Disease and pests Clear cut logging Clearing land for
agriculture Mining Global warming Introduction of invasive
species Human occupation
Clear Cut Logging & Deforestation
Clear cut logging and deforestation are a locus of concern for deciduous forests because these forests are habitat to a wide variety of animal
and plant species. Clear cut logging takes away the trees in which many animals make their
homes, making endangerment more likely, and it takes away the biodiversity in types of trees.
Deforestation, as well, takes away habitats from plants and animals to make room for houses and
industry.
Limiting Factors
Limiting factors of the temperate deciduous forest biome include:
rainfall, outward industrial expansion, deforestation etc.
