Llutxent 1 month postfire

September 18th, 2018 Leave a comment Go to comments

In early August a wildfire ignited by a lightning burned about 3200 ha, affecting mainly the municipalities of Lutxent, Gandia and Pinet (in Valencia, Spain). One month later I visited the area, and below are the main plant species that were already resprouting. There were also two species already flowering, both geophytes: Urginea (Drimia) maritima and Scilla autumnalis; they showed flowers but not the leaves (they are protanthous: flowering before the foliage appears [1]). There were also many seedling germination from the seedbank, but they were too small to identify. 

The area affected by the fire include a small marginal population of Quercus suber (cork oak; el surar de Pinet) that we had studied few years ago [2]. This oak was also resprouting (epicormically).

Notes and references

[1] The terminology of the flower/leaf phenology is a bit confusing; here is my understanding following Simpson (Plant Systematics, 2011) and Lamont & Downes (2011, Pl. Ecol. 212):

· Synanthous (syn= same time): flowers and leaves develop at the same time
· Hysteranthous: flowering occurring out of phase with leafing
· Protanthous (pro= early): flowers develop before the leaves
· Seranthous (ser= delayed): flowers develop after the leaves
