THE UNFORTUNATE withering of non-native Royal Palm trees in Iloilo City’s Diversion Road is an example of the many harsh challenges urban environments face under the strain of climate extremes like El Niño. This should be a wake-up call to local governments about the resilience of native species and their numerous benefits over non-native counterparts in urban greening efforts.
Native trees, inherently adapted to local climate and soil conditions, offer a robust alternative to their exotic peers. In the wake of the Royal Palms’ failure, the Iloilo City Government has begun replacing them with native “Dita” trees, a smart shift towards more sustainable planting practices.
Native trees offer a myriad of benefits that make them indispensable for urban environments. Unlike exotic species, they are naturally adapted to local climates, soils, and ecosystems. This ensures they thrive with minimal maintenance, making them a resilient choice amidst increasing climate variability.
Beyond mere survival, native trees support local biodiversity. They provide essential habitat and food for native wildlife, fostering a balanced ecosystem. As Executive Assistant for Environment Armando Dayrit highlighted, native trees attract biodiversity and contribute to cooler urban temperatures through their extensive canopies. This cooling effect is crucial for mitigating the urban heat island phenomenon and improving overall livability.
Culturally and historically, native trees are integral to local identity. They embody the natural heritage and hold significant cultural value, reinforcing a community’s connection to its environment.
Given these compelling advantages, it is crucial for local governments to adopt policies that prioritize the use of native trees in urban landscaping efforts. Such policies should support the sustainable cultivation of native seedlings and ensure their availability for future planting projects, coupled with public education initiatives to raise awareness about the importance of preserving native biodiversity.
Iloilo City’s plan to increase its tree canopy coverage from 10 percent to 30 percent under its Urban Tree Planting Program is good approach to urban environmental management. But it is important to ensure the long-term success and sustainability of these efforts. Involving local communities in maintenance activities will ensure the survival of native trees.
And yes, there must be a robust monitoring system to track the progress and health of planted trees, ensuring targets for canopy cover and biodiversity are met.
By institutionalizing these practices, Iloilo City can set a benchmark for other cities to emulate in ensuring a sustainable and resilient urban future.
