In page Laurel forest:

"

Laurel forests are typically multi-species, and diverse in both the number of species and the genera and families represented.[2] In the absence of strong environmental selective pressure, the number of species sharing the arboreal stratum is high, although not reaching the value of tropical forests; nearly 100 tree species have been described in the laurisilva rainforest of Misiones (Argentina), about 20 in the Canary Islands. This species diversity contrasts with other temperate forest types, which typically have a canopy dominated by one or a few species. Species diversity generally increases towards the tropics.[4] In this sense, the laurel forest is a transitional type between temperate forests and tropical rainforests.
