Fortunately the highly invasive African Love Grass (ALG) is mainly on the boundaries of the Pinnacle Nature Reserve, although some has been carried from the boundaries along the main tracks. As an illustration of the seriousness of the problem when ALG takes over, below is a photo supplied by John Fitzgerald of an infestation near the house on the North Kama property (treated in April 2011). The stake is 1.75 m tall.
