How does it help biodiversity?

While giving up herbal lands, controlled burning was discussed as a way to provide employment to keep the forests in a critical position. The University of Kobe University’s research team found that this method leads to a high biological diversity and the high rate of endangered plant species in some herbal lands compared to others, depending on the soil that grows on it.

Humans kept herbal lands for thousands of years through grazing, insistence and heartburn. All these ways to prevent forests from increasing the growth of herbal lands.

However, grazing and insistence are intense in employment and since rural areas have become increasingly population, herbal lands have disappeared all over the world. One of the results is the loss of habitats of plants and insects, including many endangered species, which depend on herbal lands.

To preserve herbal lands, however, the “described” is “the description”, which is called the land managers called the burning subject to control, as an effective option at work. But not all grassy lands are equal.

“Several studies have focused on studying the effects of various management measures on the diversity of the plant, but few researchers have taken care of the soil differences,” says the environment scientist at the University of Cuban Oshimaru Ishi.

Therefore, it has remained clear any soil is better candidates for its management through the combustion described in terms of allowing a large variety of endangered plants or plant species in general.

To settle this question, the Ushimaru team, led by a master’s student, has turned into Mount Fuji. There, at a training site for the forces of martial defense in Japan, herbal lands that cover different types of soil are kept through the prescribed burning once a year in April.

“We have noticed that there are some areas, especially on small volcanic lava flows, where the endangered species were concentrated,” Ushimaru explains the choice of the search site, allowing them to study soil factors that affect the abundance of species.

On the site, they created 100 square meters square meters across herbal lands on four different types of soil and in each specified all plants in addition to measuring a group of physical and chemical factors.

Their results, published in the magazine Plants, people, planetIt showed that herbal lands on small lava flows show high richness of species, the richness of local species and the spread of plant species listed in the red menu of herbal lands on both small and adult Skoria rocks.

They also found that the soil was different in its acidity, depth, rock covering and stones, which allowed them to conclude that these factors are important for the continuation of rare plants.

Previous studies have shown that acid soil makes it difficult for plants to eat nutrients and that shallow soil prefers slow -growing plants. Asada argues that, as shown in the re -growth of plants in herbal lands, these conditions suppress the growth of rapidly growing species and thus dominant and thus give those that are usually enlarged, and thus is a better opportunity to gain a leg.

Ushimaru summarizes, “Our study was able to identify the environments in which the herbal lands that the burn can be housed alone, a large group of endangered species.”

The team concludes its paper by saying: “Determining environments that can preserve high plant diversity through crunchy combustion not only shows the conditions for staying on the survival of herbal land plants in Japan, but it also proves necessary to preserve and restore herbal land environments and herbal lands in the future.”
