Q1: What is an invasive plant?

It is a plant species that has been introduced to a new environment, typically by human activity, and has the ability to spread and establish itself aggressively in that new habitat. Invasive plants can have detrimental effects on the ecosystems they invade, often outcompeting native plants and disrupting the balance of native flora and fauna.
