At Quinta do Lago golf courses, we are committed to preserving the natural balance and supporting local biodiversity. As part of this commitment, we are actively working to remove invasive exotic species such as lantanas (Lantana camara) and acacias (Acacia spp.). While these plants may seem visually appealing, they pose significant ecological threats to the region.
Lantanas and acacias are highly aggressive invaders, outcompeting native plant species for sunlight, nutrients, and water, which disrupts the local ecosystem. Their rapid growth creates dense thickets that smother native flora, leading to a loss of biodiversity and altering the habitat structure that local wildlife relies on. For instance, native pollinators and birds that depend on indigenous plants may struggle to find suitable food or nesting areas. These invasive species also release chemicals into the soil that inhibit the growth of native vegetation, known as allelopathy, further reducing biodiversity.
Additionally, these plants exacerbate environmental challenges by consuming excessive amounts of water, putting further strain on local water resources—an especially critical issue in the dry climate of southern Portugal. Acacias, in particular, are known to alter soil composition by increasing nitrogen levels, which favors their spread but disrupts the nutrient balance required by native plants. Both species also contribute to an increased risk of wildfires due to their high oil content and flammable nature.
By removing these invasive species, we aim to restore ecological harmony, improve soil and water health, and create an environment where native plants and animals can thrive. These actions align with our long-term goal of ensuring that our courses remain sustainable, beautiful, and deeply integrated with the natural heritage of southern Portugal.
