This is called 'controlled' or 'prescribed' burning. Usually fires in the environment are regarded as undesirable and dangerous, but fires actually fulfil an important ecological role, and animals and plants had adapted to a certain frequency and intensity of fires. The seeds of some trees or grasses germinate after forest or grass fires, as the more open conditions after a fire allows the seedlings to compete and avoid being shaded and smothered by more established trees. Unfortunately, farming and forestry practices have in many cases resulted in a reduction of fires. A reduction in the frequency of fires also allows the build up of dead wood, and when a wild fire does occur, the amount of available fuel results in very hot, large and damaging fires. Therefore, management of forests and other environments such as prairies often use controlled burns to avoid the buildup of dead organic mass and to replicate the natural fire cycle.

The measurement of pulmonary capillary wedge pressure (PCWP), which serves as a proxy for left atrial pressure and a mitral valve function indicator, is commonly utilized.
<h3>
What is pulmonary capillary wedge pressure?</h3>
- The diagnosis, prognosis assessment, and therapy of patients with suspected pulmonary hypertension (PH) and specific heart failure patients still rely heavily on right heart catheterization.
- The measurement of pulmonary capillary wedge pressure (PCWP), which serves as a proxy for left atrial pressure and a mitral valve function indicator, is commonly utilized.
- A Swan-Ganz catheter (a multi-lumen balloon catheter) with a balloon tip is inserted into a central vein and advanced into a branch of the pulmonary artery to measure it.
- The pulmonary artery branch is subsequently blocked by the balloon's inflation, which results in a pressure reading that is equal to the left atrium's pressure.

Answer: Seral stage
Explanation:
The seral community commonly known as sere. It is an intermediate stage which is found during the ecological succession in an ecosystem.
This is an intermediate stage that comes before every stage of ecological succession advancing towards its climax community.
It starts with the pioneer species and keeps on evolving until climax community is attained.
Hence, the correct answer is option C
