Pelestarian Pollinator Di Kota-Kota

Taman-taman dan alotmen (taman masyarakat) bermanfaat bagi pollinator—serangga pembawa serbuk sari dari anther (jantan) bunga ke stigma (betina) bunga sebagai proses perkawinan--dan tanaman aromatik lavender dan borage adalah sumber pangan pollinator. Sehingga kota-kota perlu mengelola pelestarian pollinator. Begitu hasil riset kolaborasi ahli pada University of Bristol, Edinburgh, Leeds and Reading, Cardiff University dan National Socio-Environmental Synthesis Center (SESYNC) (University of Bristol, 14/1/2019).

Hasil riset itu dirilis oleh Nature Ecology and Evolution (Katherine C. R. Baldock, Mark A. Goddard, Damien M. Hicks, William E. Kunin, Nadine Mitschunas, Helen Morse, Lynne M. Osgathorpe, Simon G. Potts, Kirsty M. Robertson, Anna V. Scott, Phillip P. A. Staniczenko, Graham N. Stone, Ian P. Vaughan, Jane Memmott, “A systems approach reveals urban pollinator hotspots and conservation opportunities”, Nature Ecology & Evolution, 2019).

Tim ahli itu menemukan bahwa lavender, borage, tanaman liar berbunga kuning, semak berduri, onak, dan tanaman bunga berbentuk cangkir-kuning adalah jenis spesies tanaman bagi pollinator (penyerbuk) di zona-zona kota. “By understanding the impact of each urban land use on pollinators, whether it's gardens, allotments, road verges or parks, we can make cities better places for pollinators,” ungkap Dr Katherine Baldock, NERC Knowledge Exchange Fellow dan peneliti kepala dari School of Biological Sciences dan Cabot Institute pada University of Bristol (Science Daily, 14/1/2019).

Rekomendasi riset itu antara lain meningkatkan ruang-hijau kota, taman-taman sekitar 1/3 area kota, dan taman-taman masyarakat kota. “This is the first time a new measure of management success that considers the long-term sustainability of pollinator communities, and not just individual species, has been used in a practical conservation context. Rather than simply asking about how management affects the number of pollinator species or their abundance, we also ask how potential strategies affect the ability of pollinators to cope with species losses associated with environmental change,” papar Profesor Jane Memmott, B.Sc, Ph.D, ekolog pada University of Bristol, yang memimpin Urban Pollinators Project.
