Seeding acorns for montane cloud forest restoration in central Veracruz, Mexico: practical experiences
Tropical montane cloud forests in Mexico, though rich in unique species, cover less than 1% of the country and face severe deforestation and ongoing threats, especially to oaks (Quercus spp.). Our study in the montane cloud forests in the Jamapa and La Antigua River basins of central Veracruz tested acorn seeding for forest restoration. Field trials were conducted across peri-urban and rural secondary forests, employing a range of acorn protection devices (e.g., wire mesh cages, chili pepper (Capsicum spp.) covering) and site preparation techniques to mitigate predation by rodents (Order Rodentia) and other fauna. The study also assessed the influence of microsite selection and pre-germination treatments on seedling emergence. Various rodents were the main obstacle to seeding success, exclusion devices like wire mesh cages greatly improved outcomes. Effectiveness depended on species, site, and year. Chili pepper coverings did not deter birds, and they exposed the acorns to seed predators. Successful restoration requires careful microsite selection; acorns are less preyed upon by rodents in areas with low to moderate vegetative cover. Seeds should be collected from multiple mother trees during peak fall and inspected for viability. When storage is needed, acorns should be stored under controlled conditions to maintain moisture and prevent fungal contamination. Acorn masting leads to variable seed availability modulating seed predation patterns; mast years are optimal for seeding projects. These findings underscore the need for adaptive, site-specific restoration protocols, including rapid pilot trials and monitoring of acorn production cycles.
