Like plants, animals display a range of abilities to cope with fire, but they differ from most plants in that they must avoid the actual fire to survive. Although birds may be vulnerable when nesting, they are generally able to escape a fire; indeed they often profit from being able to take prey fleeing from a fire and to recolonize burned ...
Cheirolepidiaceae (also spelled Cheirolepidaceae) is an extinct family of conifers.They first appeared in the Triassic, and were a diverse and common group of conifers during most of the Mesozoic era, primarily at low latitudes, [1] where they often formed a dominant element of the vegetation. [2]
Unusually for a pine, the cones normally point forward along the branch, sometimes curling around it. That is an easy way to tell it apart from the similar lodgepole pine in more western areas of North America. The cones on many mature trees are serotinous. They open when exposed to intense heat, greater than or equal to 50 °C (122 °F). [16]
Unlike animals, plants are not able to move physically during a fire. However, plants have their own ways to survive a fire event or recover after a fire. The strategies can be classified into three types: resist (above-ground parts survive fire), recover (evade mortality by sprouting), and recruit (seed germination after the fire).
Closed-cone forests rely on regular but infrequent fires, often stand-replacing crown fires. Fire opens up space in the canopy or clears away litter on the ground, so there is less competition for germinating seeds. Thus, the fire is an advantageous time for trees to drop their seeds.
This pine is one of the most fire-resistant conifers in the world, due to several beneficial adaptations. [ 11 ] [ 12 ] [ 13 ] In particular, Pinus canariensis is one of the few pine species that can epicormically resprout after losing its needles in a fire.
Prostrate slow-growing conifer, 1–2 m (3 ft 3 in – 6 ft 7 in) in width 1–1.5 mm (0.039–0.059 in), dense, opposite and decussate along branchlets, giving a square appearance: Male and female cones on separate plants. Male cones small and terminal. Female cones terminal and fleshy and red when mature: The only natural prostrate conifer
Cupressaceae is a widely distributed conifer family, with a near-global range in all continents except for Antarctica, stretching from 70°N in arctic Norway (Juniperus communis) [3] to 55°S in southernmost Chile (Pilgerodendron uviferum), further south than any other conifer species. [4] Juniperus indica reaches 4930 m altitude in Tibet. [5]
