Põhiliigil

Põhiliigil is an Estonian term that translates to "main species" or "primary species." It refers to the dominant or most abundant organism within a specific ecological community or habitat. This species plays a crucial role in shaping the environment and influencing the populations of other organisms present.

The identification of a põhiliigil often involves considering factors such as biomass, population density, or ecological impact. For instance, in a forest ecosystem, a particular tree species might be considered the põhiliigil if it constitutes the majority of the trees and provides essential habitat and food sources for numerous other plants and animals. Similarly, in a marine environment, a certain type of coral or seaweed could be the põhiliigil due to its foundational role in the reef structure or its contribution to primary production.

Understanding the põhiliigil is important for ecological studies and conservation efforts. Changes in the population or health of the põhiliigil can have cascading effects throughout the entire ecosystem. Monitoring and protecting the main species are often key strategies for maintaining biodiversity and the overall stability of a habitat.
