Dear fire/urban threaders,
Since both grazing and fire have lots of variable effects depending on
frequency, intensity, seasonal timing, weather conditions etc, I am
troubled by assertions that fire achieves effects that are not achieved by
grazing. This may indeed be true, but to state that
No. We already understand enough about geochemistry, about tissue damage, about
organismal development to understand that fire and grazing often can have
effects not achieved by the other. We also know that there are similarities in
their effects. If you're waiting for experimental evidence
Another angle, which might in part have been the intent of the interviewee in

including plant community structure, which are dependent on fire, at least in a
natural ecological context. We know that in southeastern U.S.
Your commentary is interesting. In North America, we do consider the prairies
and their plants to be adapted to grazing, and that is true of grasses in
general around the world. They have meristems distributed in the plant body so
that they grow from the base, and regenerate if cut back

I don't know if this rises to the level of knowledge, but I have
often heard that the cones of certain pines won't open to release their
seeds unless toasted in a fire. It seems that it would take just the right
amount of fire, though, because toasting for too long would surely
Wayne, I have heard this fire dependent terminology in reference to both
community types and specific plants. However, most often it has been in
reference to community types that included dominant fire adapted species. I
also have heard more convincingly that lodgepole pine, _Pinus contorta_,

Martin's point is well made. Generally it is more accurate to state that a
plant community is fire-dependent, and one could state that such an assemblage
of species, or a particular plant species, if fire-adapted. Indirectly,
however, a plant species as Martin describes could be said to be
The list goes on and on and on. Bulbostylis in Venezuelan savannas flowers

obligately depend on fires to trigger flowering; many other plants in other
systems flower profusely a year or two after fires (e.g., Xanthorrhoea,

questionable assumptions that y'all can help me clear up.
