For\ndeveloping a better methodology of indirect greenhouse gas (GHG) emission\nassessment in peatlands in Latvia, a new project was implemented by the Institute\nfor Environmental Solutions<\/a> (IES) in\ncooperation with Nature Conservation Agency<\/a>\nof Latvia. The project was financed by the Latvian Environmental Protection\nFund. The project \u201cRemote sensing methodology for monitoring greenhouse gas\nemissions in wetlands\u201d (No. 1-08\/146\/2018) is aimed at using detailed remote\nsensing data and GEST methodology in assessment of GHG emissions.\n\nProject results were presented at the seminar\n\u201cMethods for measuring greenhouse gases in peatland and other ecosystems\u201d\norganized by IES on August 8, 2019, in C\u0113sis, Latvia. In the seminar, M\u0101ra\nPakalne (University of Latvia) introduced the aims and importance of the LIFE Peat\nRestore project which contribute to improving the knowledge of direct and\nindirect GHG emission assessments in Latvia. LIFE Peat Restore expert L\u012bga\nStrazdi\u0146a (University of Latvia) explained the principles of GEST methodology,\nits pros and cons in situations in Latvia which differ from Germany in climate\nand vegetation aspects whereby studies of new GEST types are necessary. Both\npresentations are available here (1<\/a>, 2<\/a>), more detailed information about the seminar\nis available here<\/a>.\n\n\n\n<\/p>\n\n\n\n

The\nobjectives of the project were to estimate the GHG emissions in five pilot\nsites using remote sensing data. The study areas included alkaline fens in Lake\nEngure Nature Park, Madie\u0161\u0113nu and Nam\u012bt\u0113nu Mire in Augstroze Nature Reserve\n(all are also LIFE Peat Restore project sites), as well as P\u0113terezera and\nKuk\u0161upe inter-dune mires in Sl\u012btere National Park and Sudas-Zviedru Mire in\nGauja National Park, where peatland restoration was performed within the LIFE\nWetlands<\/a> project.<\/p>\n\n\n\n

Remote\nsensing data of the project areas was collected in June 2018, using airborne\nsurveillance and environmental monitoring system (ARSENAL) that includes\naircraft equipped with hyperspectral data sensor and LIDAR. During summer\nperiod, field data of GEST vegetation classes as a reference data for further\nremote sensing data analysis were collected. For all classified vegetation\nunits corresponding GEST types were found. <\/p>\n\n\n\n

At the result\nof GEST mapping, ten GEST-types were classified. The most common in all project\nsites are Wet tall sedges reeds and Wet peat moss hollows resp. flooded peat\nmoss lawn, which represent fen and transition mire vegetation. The largest area\nwas taken by Wet peat moss lawn that dominates in raised bog ecosystems.<\/p>\n\n\n\n

Different scenarios were modelled\nto measure the significance of planned or implemented peatland restoration\nactions in terms of GHG emissions. It was calculated that positive effect can\nbe expected in all sites, for example, in degraded area of Madie\u0161\u0113nu Mire\n(Augstroze Nature Reserve) change of GEST-type and CO2<\/sub> emission\ndecrease for 56% were predicted within 50 years. Similar amount (CO2<\/sub>\nemission decrease for 53%) was measured in Sudas-Zviedru Mire, while it was\neven higher (for 91%) in P\u0113terezera inter-dune mire after tree removal.\n\n\n\n<\/p>\n\n\n\n
