Based on present-day rainfall maps, however, Weigand estimated that Ireland had an original rain forest of 143,400 ha, and GIS-derived calculations added 13,900 ha for a total of 157,300. Some forests have been allowed to regenerate naturally in the western portion of the island. Killarney National Park (8500 ha) is one such area under protection within the rain forest zone epub. Approximately 709,500 ha of subtropical rain forest were found along the Black Sea region of former Soviet Georgia and in the adjacent Batumi Oblast (Map 3 - Eastern Black Sea, p.19).

Other colonial commentators, like the visiting Norwegian zoologist Carl Lumholtz, wrote less lushly, but still expressed admiration for the natural wonders of the rainforest. They also conveyed the clear message that while the rainforests were beautiful to behold, they were not a nice place to live in. Alongside aesthetic appreciations of the rainforests, these early observers expressed decidedly utilitarian aspirations online. Instinct theory has to be dealt with very cautiously, lest it devolve into outright sociobiology. Kropotkin’s rather loose attribution of ‘social instinct’ to animals generally in order to validate mutualism is particularly troubling, in my view, not only because it is based on a highly selective study of animals — he tends to ignore a host of solitary animals, including highly advanced mammals Empire of the Beetle: How read online read online.
