Climate plays a key role in determining the distribution and persistence of conifers in their natural habitats. Climates change over both contemporary and geological timescales and in response to this, some species may become locally or even globally extinct or they may disperse to more suitable areas.
Over shorter time scales, the longevity and resilience of many species may allow them to persist in the same area. In the recent past, these processes generally occurred within a landscape locally impacted by humans but more recently, large areas of natural vegetation have been converted for other uses. Ecosystems have become fragmented and degraded, many individual species have been intensively exploited and the introduction of alien plants, animals and diseases has also caused significant problems. Against this backdrop, climate changes associated with global warming such as increases or decreases in precipitation levels and average temperatures are having increasing direct and indirect effects on many conifer species and their habitats. Impacts include more intensive or prolonged droughts, higher frequency and intensity of fires and increases in pests and disease.
There are 34 taxa in the category – Climate change:
Endemic to eastern China in Zhejiang Province where only a handful of mature individuals survive… Read full species entry >
A relictual species confined to the Santa Lucia mountains of southern California. It is potentially susceptible to indirect effects of climate change and any further change in its status could lead to a listing as 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 >
Abies pinsapo var. pinsapo
One of two varieties of the Spanish fir restricted to three areas of southern Spain where in the last 45 years large areas of forest have been lost mainly as a result of fire.… Read full species entry >
Endemic to the Mt. Panié range in northern New Caledonia where recent research has found that the decline and loss of old-growth trees is probably due to a combination of factors including root damage by feral pigs, pathogen attack and climate change.… Read full species entry >
One of 13 species of Araucaria endemic to New Caledonia where it is restricted to less than five locations. There has been a recent decline in the health of some high altitude stands.… Read full species entry >
Sorry, awaiting image
One of the tallest tropical conifers, reaching heights of up to 90 m. Endemic to Papua New Guineawhere many original stands have been logged or burnt but the uncertainty in quantifying the extent of decline menas that it is currently assessed as Near Threatened.
