1 COMMON PROBLEM INVASIVE IN KLOOFENDAL NATURE RESERVE Compiled by Karin Spottiswoode for the Friends of Kloofendal June 2014, updated July 2016 This list includes the major problematic invasive plants in Kloofendal. As there are so many, the lesser problematic invasive plants have not been included in this document. So far 64 problematic species in Kloofendal have been listed This is a “working document”. The contents will need to be updated from time to time. This document on invasive problem plants in Kloofendal is based on the list of declared alien & invasive species, published in the Alien and Invasive Species Regulations (AIS), National Environmental Management Biodiversity Act (Act no 10 of 2004) as published in the Government Gazette, 1 August 2014 REFERENCES BROMILOW, C., 2010.
