Here are some pictures of R. dentata from the Cedar Mountains. We only found one very small population of about 15 plants growing in about 10 square meters. We only found them at this single spot! A fire is definitely necessary to ensure the survival of the plants in that location. I hope, you like the pictures.
Lightning is the most common cause of periodic veld fires. South-easterly winds predominate in the summer and also contribute to the high veld fire risk. ... Extremely hot fires which are disastrous for adult trees are limited, and instead cooler more frequent burning is practised.
I wonder how the management of the area by "frequent burning" is done and how often.
