Question

Почему на выгоревших участках леса не растут ёлочки сосенки кедры

Answer 1

Аномально жаркое лето на территории нашей страны оставило о себе недобрую память в виде пепелищ от лесных пожаров. До сих пор никто не может точно сказать, сколько гектаров леса сгорело за эти два месяца. Тем не менее, если посмотреть на фотографии, сделанные на месте пожаров, то сразу становится ясно — урон лесному хозяйству нашей страны нанесен немалый. Пройдут годы, прежде чем на месте унылых гарей вновь поднимется стена лесных исполинов.

Why Trees Like Spruce, Pine, and Cedar Don't Grow on Burned Forest Areas

When a forest area is burned, it can have a significant impact on the regrowth of certain tree species like spruce, pine, and cedar. The reasons for this are as follows:

1. Soil Conditions: - The soil conditions in burned areas can be significantly altered, affecting the ability of certain tree species to grow. The heat from the fire can lead to changes in soil structure and composition, making it less conducive for the growth of specific tree species.

2. Seed Viability: - The intense heat from a forest fire can destroy the seeds of certain tree species, reducing their viability for germination and growth. This can hinder the natural regeneration of trees like spruce, pine, and cedar in burned areas.

3. Competition from Other Species: - After a forest fire, other plant species, including fast-growing grasses and shrubs, may quickly colonize the burned area. This competition for resources such as sunlight, water, and nutrients can limit the ability of tree species like spruce, pine, and cedar to establish themselves in the post-fire environment.

4. Regeneration Strategy: - Some tree species, including spruce, pine, and cedar, may have specific regeneration strategies that are not well-suited to the conditions created by a forest fire. For example, these species may rely on seedlings being sheltered by the canopy of older trees, which is lost in a fire-damaged area.

In summary, the inability of trees like spruce, pine, and cedar to grow on burned forest areas can be attributed to changes in soil conditions, reduced seed viability, competition from other plant species, and the mismatch between the regeneration strategy of these trees and the conditions created by forest fires
