 Looking
at the number of species in the southwestern Cape in more detail, we find that.
The Lost flora! The number of species on the Cape Flats has gone from
about 20 species to 10. We have discussed these extinctions already, but it should be
pointed out that many of the surviving species are almost extinct there as well!
The centre of rarity in the Cape Flora remains as Kogelberg.
However, the centre of species richness has moved from Howhoek to
Villiersdorp. Before the project began Howhoek had 59 species making it the centre of
protea richness inthe Cape Flora. Now, it has 68 species - a significant increase.
However, Villiersdorp has 75 species -many more. This is thus the heart of the Cape Floral
Kingdom!
Although Villiersdorp is the richest grid square with 75 species, 10 of
these species were not found there during the Protea Atlas Project. If we only consider
species atlassed, then the richest Grid Square is Kleinmond with 67 species (Villiersdorp
has 65!). We obvioulsy need to try and investigate those old herbarium records more
carefully!
