Indigenous vegetable garden to protect species

The declining native population can be planted in urban green areas. Researchers at the German Institute for Integrated Biodiversity (IDV), Martin Luther University Halle-Wittenberg (MLU), the University of Leipzig and other institutions are discussing how to use this great potential for species conservation. In their most recent study published in the journal Natural sustainabilityThey recommend practical gardening techniques to reorganize the horticulture industry and reverse plant failures.

Despite international efforts to preserve biodiversity, many plant species are still declining. In Germany, this includes 70 percent of plant species, one-third (27.5 percent) endangered and 76 species considered extinct. Much of this loss may be due to the reduction of natural housing, partly due to urban sprawl. Ten percent of the total area of ​​Germany, for example, is residential.

However, even though they are untouched – these settlements can be a safe haven. After all, these places include millions of private gardens, balconies and green roofs, as well as parks and other public green spaces. Researchers at IDV, Hale and Leipzig Universities and other institutions have suggested that these available spaces be used for garden conservation.

This horticultural practice especially encourages the declining indigenous species. Indigenous plants are plants that occur naturally in their habitat, adapt to specific areas and coexist with other species. While vital to the functioning of our ecosystems, indigenous plants are severely damaged and in need of protection. “Gardeners always play a role in propagating plant species, so why not help bring back many of the extinct native species?” Interview with Josie Segar, lead author of iDiv and MLU. “Public and private gardens and green spaces may play a central role in maintaining plant diversity, but to do so would require a rethinking of the horticultural industry.”

According to the researchers, the economy already has the potential to rejuvenate the garden as well as the industry. Horticulture is an important business sector in many countries. For example, in Germany 8. 8.7 billion was spent on plants in 2018; The trend is growing. During the cholera epidemic, per capita expenditure on plants increased by 9 percent. Public awareness of biodiversity has increased dramatically in the past. Planting the declining native species also has obvious benefits. Many of them are suitable for dry soils and are better able to withstand drought due to climate change than most of the varieties currently used in gardening. If they are widely available in backyard gardens, these factors could increase the demand for plants suitable for gardening, the authors said.

The researchers said that the key to expanding the conservation garden is to create a strong link between the major horticultural industry and the domestic seed market. Certified indigenous seed production and marketing should be promoted through financial means and policy support such as reduced VAT. Product labels in gardening centers can point out the benefits of gardening protection and influence curves of interest. Appropriate standards for awarding public contracts to horticultural companies will help to encourage declining plant species in public green spaces. Practical research details of declining plant species in the region, as well as planting concepts and seed mixing, can promote scientific gardening. In addition, key actors such as plant parks, universities, conservation associations, neighborhood cooperatives, and public bodies may disseminate important knowledge about plant production and care.

“Environmental gardening focuses on traditional horticulture, facilitates structural change. Large-scale implementation does not require extensive changes to existing conservation architecture,” said Dr. Ingmar Stewde, senior author at iDiv and Leipzig University. “Indeed, when planting green spaces, it uses existing economically viable structures to encourage the use of declining species. In an ever-increasing urban world, this could increase the real and comprehensive conservation of natural resources for citizens.”
