What are the features of temperate broadleaf and mixed forest ?
Answers
typify the composition of the Temperate Broadleaf and Mixed Forests (TBMF). Structurally, these forests are characterized by 4 layers: a canopy composed of mature full-sized dominant species and a slightly lower layer of mature trees, a shrub layer, and understory layer of grasses and other herbaceous plants.

Structurally, these forests are cahracterized by 4 layers: a canopy composed of mature full-sized dominant species and a slightly lower layer of mature trees, a shrub layers, and understory layer of grasses and other herbaceous plants.
- In contrast to tropical rain forests, most biodiversity is concentrated much closer to the forest floor.
- TBMF are richest and most distinctive in Central China and Eastern North America, with some other globally distinctive ecoregions in the Caucasus, the Himalayas.
Biodiversity patterns:
Most dominant species have widespread distributions, but in many ecoregions there can be large number of ecoregional and local endemics.
Minimum requirement:
Large native carnivores require large natural landscape to persist, periodic large-scale disturbance event such as fire necessiate the conversion of large blocks of forests.
Sensitivity to disturbances:
Certain species are highly sensitive to habitat fragementation such as breeding songbirds exposed to parasitism or elevated nest predation: the loss of large native predators has many cascading impacts on forests structure and ecology.
