Temperate forest Temperate forest Environment Winter in the temperate latitudes can present extremely stressful conditions that greatly affect the vegetation The days are shorter and temperatures are low so much so that in many places leaves are unable to function for long periods and are susceptible to damage from freezing These conditions reduce the photosynthetic activity of the
Get PriceTemperate Forest Soils Forest soils developed under temperate climate usually have higher organic matter because they have lower temperature which slow down the decomposition rate However these soils are highly weathered due to the seasonal temperature and precipitation rate along the year
Get PriceTemperate forests are very variable and it is in them where the largest number of deciduous trees on the planet can be found You can also find mixed forests with coniferous trees deciduous broadleaved and broadleaved green as well It is a forest that contains a temperate forest biome which are considered to be the most altered on the planet Temperate deciduous forests are forests
