Climate change is disrupting the Canary Islands' ecosystems, shifting the blooming period of almond trees, traditionally in January. The changes, closely watched by scientists, beekeepers, and farmers, are particularly impacting species and habitats.
The Canary Islands, with ecosystems adapted to insularity and subtropical climate, are experiencing changes due to rising temperatures and increased drought. On Gran Canaria, green areas are retreating inward as the island adjusts to the changing environment.
Almond trees, or "almendreros", require a certain number of 'chilling hours' (between 0 and 7°C) to reproduce. This triggers the end of their dormancy, leading to a spectacular display of flowers. However, climate change may threaten this tradition, raising questions about the future of these stunning January blooms.
Antonio Quesada, a Biology graduate and member of the Gran Canaria Beekeepers Association (APIGRANCA), highlights the natural rhythms of nature. He advises caution, suggesting that the delayed flowering of almond trees should be a concern, but not a cause for panic. Quesada suggests that occasional delays in plant flowering can be part of natural cycles, rather than indicative of long-term trends.
However, Quesada also notes that heat during flowering periods could prevent fruit formation and disrupt the behaviour of pollinators. Beekeepers are concerned about the potential scarcity of flowers due to low rainfall, which could impact insect food sources.
Experts urge vigilance and stress the importance of observing broader temporal patterns before raising alarms, as nature can exhibit cyclical variations. The delayed blossoming of almond trees serves as a warning, highlighting the urgent need to address climate change for the health of ecosystems and traditional celebrations.
