Relationship to other branches of ecology

Forest ecology is one branch of the biotically-oriented fields of ecology (as opposed to a

fields oriented towards the organisational level or complexity of ecological systems, for

example 


population

 or 


community ecology

). Thus, forests are studied at a number of

organisational levels, from the individual 

organism


 to the ecosystem. However, as the term

forest


 connotes an area inhabited by more than one 

organism


, forest ecology most often

concentrates on the level of the 

population

community



 or ecosystem. Logically, 

trees


 are an

important component of forest research, but the wide variety of other life forms and 

abiotic

components

 in most forests means that other elements, such as 

wildlife


 or 

soil


 

nutrients

, are

often the focal point. Thus, forest ecology is a highly diverse and important branch of



ecological study.

Forest ecology shares characteristics and methodological approaches with other areas of

terrestrial plant

 ecology, however, the presence of trees makes forest ecosystems and their

study unique in numerous ways due to the potential for a wide variety of forest structures

created by the uniquely large size and height of trees compared with other terrestrial plants.

Community diversity and complexity




Since trees can grow larger than other plant life-forms, there is the potential for a wide variety

of forest structures (or physiognomies). The infinite number of possible spatial

arrangements of trees of varying size and species makes for a highly intricate and diverse

micro-environment in which environmental variables such as 

solar radiation

, temperature,

relative humidity

, and 


wind speed

 can vary considerably over large and small distances. In

addition, an important proportion of a forest ecosystem's 

biomass


 is often underground,

where soil structure, 

water quality

 and quantity, and levels of various soil nutrients can vary

greatly.

[5]


 Thus, forests are often highly 

heterogeneous

 environments compared to other

terrestrial plant

 communities. This heterogeneity in turn can enable great biodiversity of

species of both plants and animals. Some structures, such as tree ferns may be keystone

species for a diverse range of other species.

[6]


A number of factors within the forest affect biodiversity; primary factors enhancing wildlife

abundance and biodiversity was the presence of diverse tree species within the forest and

the absence of 

even aged timber management

.

[7]


 For example, the 

wild turkey

 thrives when

uneven heights and 

canopy

 variations exist and its numbers are diminished by even aged



timber management.

Forest management techniques that mimic natural disturbance events (variable retention

forestry

[8]


) can allow community diversity to recover rapidly for a variety of groups including

beetles.
