Deciduous forests extend throughout much of the northern hemisphere, as well as in some parts of Argentine Patagonia. It is a very common type of forest, belonging to the temperate hardwood forest biome. It is a well-known type of forest inhabited by a great variety of species, both animals and plants, as well as other kingdoms of nature.
If you want to know what is a deciduous forest, its characteristics, flora and faunaJoin us in this interesting article by Green Ecologist.
Deciduous forest characteristics
We will start by clarifying what a deciduous forest is. The most distinctive feature of a deciduous forest is that it is forests where a good part of the plant species lose their leaves every year, in the cold and dry season. When we talk about deciduous forests, the common thing is that we refer to a temperate deciduous forest, although there are also tropical ones, which can be called jungles or deciduous forests. Apart from the comments, these are the main characteristics of deciduous forests:
The 4 seasons of the year in the forests
In this environment, the biome goes through the four seasons of the year, which is why its trees suffer adaptations and cycles linked to seasonal changes. That is, they lose their leaves in the winter months and make them sprout again with the arrival of spring. Learn more about it in this other article about Why the seasons exist.
Deciduous forest climate
The climate of the deciduous forests tends not to be extreme, although in the continental climate it offers quite marked thermal variations between night and day, as usual. Here, it is common for the temperature to drop below zero in the cold months, and for the average temperature to remain above 10 ºC in summer. In the oceanic climate, as is common, the thermal variations are less thanks to the influence of the marine winds.
Characteristics of deciduous forest trees
Being made up of deciduous trees, they enter a dormant season in the cold months, which drastically reduces their nutrient consumption and contributes to their renewal. Thanks to this, they tend to be very fertile forests in general terms, with a large amount of nutrients of all kinds.
It is also important to note that many of the trees in these forests have sap, which they use as a means of preventing freezing during the colder months. Many plant species can extend their growing season up to six months, thanks to the mild and beneficial conditions it offers. As the trees grow each season for a few months and then retreat to rest, it can be seen in the sections of their trunks the so-called growth rings: concentric circles in which each line represents a life cycle of the plant. In tropical deciduous forests these rings do not correspond to an exact year, since the growth is not the same in each season, so they cannot be used to calculate their age.
Unfortunately, this is one of the types of forest that has suffered a increased deforestation at the hands of man throughout the world, especially because of urbanization and agriculture, which seeks to take advantage of its fertile and rich soils. Uncontrolled logging has left a large number of fauna species without habitat and displaced, and their disappearance is especially noticeable in the territories of Europe and North America, where human progress has wreaked havoc.
Deciduous forest flora
The deciduous forest plants They depend to a great extent, of course, on the region in which it is found, since these forests are widely distributed throughout the planet. These are some of the deciduous forest trees:
In North America and Europe we find trees such as:
- The hague (Fagus sylvatica)
- The common oak (Quercus robur)
- Brown (Castanea sativa)
- Hornbeam (Carpinus betulus)
- Birch (Betula spp.)
In Asia, species such as:
- Liquidambar formosana
- Pistacia chinensis
- Quercus variabilis
- Quercus dentata
- Quercus acutissima
In South America we also find species of the genus Quercus, as well as some Nothofagus. Examples of the latter are:
- The raulí (Nothofagus alpina)
- The maulino oak (Nothofagus glauca)
- The ñire (Nothofagus antarctica)
Coniferous deciduous forests dominate the gymnosperm plants, especially those of the genus Larix. Learn more about What are gymnosperm plants, their characteristics and examples with this other article In this area it is common to find:
- Larix sibirica
- Larix gmelinii
- Larix decidua
- Larix cajanderi
Lastly, we have the tropical deciduous forests. In them it is very common to find:
- Malvaceae
- Legumes
- Bignoniaceae
- Burseráceas
The latter are typical of the American tropics. In addition, teak (Tectona grandis) and highly appreciated both for its wood and for the oil that is extracted from it, used in polishing other woods.
Deciduous forest fauna
Finally, we will talk about the fauna of the deciduous forests. Regarding this aspect, it must be taken into account that the deciduous forest animals They present a great diversity, although there are very characteristic species that are worth mentioning.
In Europe we find deciduous forest animals such as:
- The European brown bear
- The wolf
- The Fox
- The boar
- The common deer
- The bison
In North America these other animals stand out. In addition, it should be noted that these can be seen from the most temperate zones to cold regions where there are coniferous forests.
- Black bear
- The Puma
- The moose
Finally, in tropical deciduous forests we find:
- E collared peccary
- Howler monkey
- The ocelot
- The guacharaca
- The Mapanare Serpent
