Newlands Forest lies at a natural transition zone between endangered
Granite Fynbos and
Peninsula Shale Fynbos, in an area that also originally supported large
indigenous forests. In the late 1800s, much of the indigenous forests were felled, and the fynbos cleared, to make way for
commercial pine plantations, which still remain and account for the remainder of the land.
Peninsula Granite Fynbos This is an
endangered vegetation type, which can still be found on the southern edges of Newlands Forest. This ecosystem is endemic to the city of
Cape Town and occurs nowhere else in the world. Existing only on the Cape Granite Formation, it naturally assumes the form of medium-dense tree vegetation, dominated by a variety of
Protea and
daisy species. The striking and iconic
Silvertree grows in this vegetation type and a small population of these massive proteas can still be seen at Newlands forest. Historically this ecosystem supported a great many wild animals and there are at least 9 plant species which occur nowhere else in the world. This vegetation is severely threatened, mainly by invasive alien plants. A total of 13 of this ecosystem's plant species are classed as
endangered, two of them
critically. One local species, the
Wynberg Conebush, is now
extinct. •

Peninsula Shale Fynbos This is actually a type of
Cape Winelands Shale Fynbos, which is mainly found far to the east of Cape Town in the
"Boland" region. The patch that occurs around Newlands Forest is a natural outlier, isolated in the middle of Cape Town. The soils are naturally poor and slightly acidic but the biodiversity is incredibly rich. The vegetation consists of a diverse array of
Protea,
Erica,
geophyte and
daisy species, as well as some
endemic species. In the moister areas, the
Ericas predominate over the other plant groups. Along with the Granite Fynbos, this is by far the most diverse and richest in species of the ecosystems at Newlands Forest. As it typically grows on lower mountain slopes, which tend to be developed for housing or cultivated for farming, this vegetation is incredibly vulnerable. A total of 23 of this ecosystem's plant species are officially
threatened, 7 of which are classified as
endangered. •

Pine and Gum plantations In Newlands Forest, there are also 2 types of commercial plantation, Pines (
Pinus radiata,
Pinus pinaster) from Europe and America, and Gums (
Eucalyptus lehmannii) from Australia. Over many decades, large swaths of the Cape Peninsula were cleared of their indigenous vegetation types to make way for commercial logging, and these two species were imported and cultivated en masse to supply the Cape timber industry. These species were chosen for their fast growth, the quality of their wood and their straight uniform growth which made them easy to harvest. However, they rapidly spread and became invasive. When the logging was eventually stopped, the final crop of trees was allowed to remain un-harvested, and today forms an important recreational area for the inhabitants of the surrounding suburbs. Both the pines and the eucalyptus("gum") trees are Category 2 invasive weeds. They rapidly seed into the surrounding
indigenous forests and
fynbos, then gradually outgrow and kill these ecosystems. Consequently, on-going maintenance is necessary, to keep these invasive trees contained within the plantations. In addition, the leaf-litter of pines and gums changes the pH of the surrounding soil, poisoning other plant life. The trees may have evolved this feature to kill competing plants, and it is so effective that pine or gum forests in southern Africa eventually turn into monocultures or "green deserts". Consequently, there is also a policy in place to regularly "thin" the remaining plantations, in order that some other species can survive in between the pines.
