Invasive and opportunistic plants

Index card

Introduction

In pasture meadows, when cattle pressure diminishes, plants regain space.
One of the earliest colonizers is this tall shrub, from the genus Papilionaceae, or the genus: the broom (Sarothamnus scoparius) Its spread is favored by creams used by shepherds to promote tender grass. In spring it blooms abundantly in yellow and is very aromatic. Small leaves, always green and up to 2-3 m high.
Another plant we see is thistle (foto). It grows on heavily nitrified soils, where herds have been around for a long time and their droppings have brought a lot of nitrogen to the sun.
A more current invasive plant is the yellow-headed narrow-leaved ragwort (Senecio inaequidens): a small plant with a very thin leaf and a yellow daisy-like flower but with longer, thinner petals. Get off the road. Currently their control is a problem everywhere.
