As a result of an explosive growth rate in the human population over the last 50 years there has been a steady drift of people out of the cities and out of the countryside into the suburbs. It is estimated that 60% of the Earth's population will live in urban areas by 2030.
Hence these increasing population densities and mounting development pressures are causing large tracks of land in the immediate surroundings of urban areas undergoing a process of what is known as urbanisation. This phenomenon directly alters forest ecosystems by removing or fragmenting forest cover. It indirectly alters forest ecosystems by modifying hydrology, altering nutrient cycling, modifying disturbance regimes, and changing atmospheric conditions. Land changes associated with urbanization also drive climate change and pollution, which alter properties of ecosystems at local, regional, and continental scales. Urbanisation has a serious affect on conifers throughout their range in both temperate and tropical regions of the world. Some of this associated disturbance is so severe that it has led to conifer species becoming Critically Endangered.

Abies pinsapo var. marocana
The Moroccan fir is restricted to two small forests in the Rif Mountains of northern Morocco where over a period of 60 years it has suffered a 70% decline.… Read full species entry >
A widespread species that only ever occurs in small isolated populations. It is currently assessed as Near Threatened due to range wide deforestation.… Read full species entry >
A widespread species that has been exploited for timber and resin. Difficulties in estimating the extent of its decline and a lack of information about its staus is some parts of its range have resulted in an assessment of Near Threatened.… Read full species entry >
Native to mountains adjacent to the north-eastern Mediterranean coast in Turkey, Syria and Lebanon. Threats include pathogens, fire, urbanisation, selective felling, activities associated with winter sports and grazing.… Read full species entry >
A difficult to identify species that is likely to be widespread in China. Past exploitation for medicinal use and deforestation have resulted in an an assessment of Near Threatened.… Read full species entry >
