Agri varsity’s Miyawaki grove becomes research hub for soil, biodiversity studies
As the world observes Nature Conservation Day on Monday, Punjab Agricultural University (PAU) showcases a vivid testament to green commitment through its Miyawaki forest near Gate No. 1 which is now a flourishing grove of over 42 native species, including kikkar, phalsa, sohanjna, pappdi and lasuda. But beyond just the visual appeal, the forest now also offers researchers a rare opportunity, to assess whether rapid afforestation can truly deliver long-term ecological gains.
Launched under the CSR initiative of Vardhman Special Steel and facilitated by EcoSikh, the forest was designed not just as a green patch, but as a controlled research study. A conventionally spaced mini-forest planted nearby allows scientists to compare growth patterns, biodiversity impact and seasonal resilience.
“The PAU planted Miyawaki forest on one acre during 2024. More than 10,000 plants, belonging to 40 species (traditional trees of Punjab), have been planted. This will serve as germplasm bank for the future. Endangered plant species are being maintained and can be multiplied as and when needed. Besides, it is very useful for the students in helping them identify plants. Furthermore, several studies can be taken up with respect to changing scenarios of soil health and soil microflora,” said PAU Vice-Chancellor Dr Satbir Singh Gosal.
The three-foot deep mulch of paddy straw and farmyard manure used in the forest enriches soil organic content, requiring minimal irrigation and providing an ideal environment for studying soil microflora and fauna, added Dr Gosal.
“This is not about choosing sides—it’s about understanding what works best for Punjab’s soil, climate and biodiversity. We’re observing how species compete, co-exist and respond to natural conditions. The goal is to inform future afforestation policies with real data,” said an expert from the Department of Forestry.
The Miyawaki technique, developed by Japanese botanist Dr Akira Miyawaki, involves planting native species in tight clusters to mimic natural forest layers. Globally, it’s hailed for creating dense green cover in small spaces, especially in urban areas. But experts remain divided on its long-term viability. Some argue that dominant species may outcompete others over time, while others question its carbon sequestration claims.
At the PAU, the forest has been handed over to multiple departments for parallel studies—ranging from biodiversity and canopy development to soil health and maintenance needs.
As Punjab grapples with rising pollution, shrinking green cover and climate stress, the findings from the PAU’s twin forest plots could shape how industries, schools, and civic bodies approach afforestation.
“From flowering shrubs to towering trees, from medicinal herbs to native flora, the PAU’s green journey is growing deeper roots every season. These efforts are not just beautifying the campus; they are reviving ecological balance, nurturing biodiversity and planting seeds of change in every student who walks these grounds,” added Dr Gosal.
