1. Background 1.1 The main stages of the TMS project Transboundary environmental monitoring is a necessary prerequisite for any sound and informed, national or trilateral, decision on the management, protection and development of the transboundary Prespa Park. This has been enshrined in the Prespa Park Strategic Action Plan in 2002. The GEF/UNDP Prespa Park project, which started in late 2006, has included activities on the setting up of a transboundary monitoring system. The current project for the development of a Transboundary Monitoring System (TMS) for the Prespa Park area is being implemented since October 2007 by the SPP, in coordination with the relevant component of the GEF/UNDP Prespa Park project. The SPP secured funds for setting up the TMS in the Prespa Park by an alternative donor (WWFGreece). The Monitoring and Conservation Working Group (MCWG), composed of representatives of the primary relevant stakeholder institutions in Albania, Former Yugoslav Republic of Macedonia and Greece, was established in October 2007 to guide the overall monitoring process (both GEF and WWF-Greece funded components), and ensure consensus at all stages of development of the TMS. The TMS project is structured in 6 main Stages, according to the initial plan agreed between SPP and the GEF/UNDP Project, and validated by the MCWG in its first meeting (October 2007), and to the Memorandum of Understanding signed between SPP-UNDP. 1. 2. 3. 4. 5. 6.

Preparatory Stage (Oct 07 -Jun 08; completed) Expert Study on the TMS (Sep 08 - Oct 09; completed) Purchase and Installation of Equipment (to be determined) Pilot application of the TMS (Dec 09 - Dec 10) Adjustment of the TMS (Dec 10 - May 11) Final approval of the system (May 11 - Sep 11)

Stage 1 (Preparatory Stage) was implemented between October 2007 and June 2008. Stage 2 on the development of the expert study started in September 2008 and was finalized at the end of October 2009. Stages 3-6 are to be developed and elaborated in detail according to the recommendations of the TMS expert study, the guidance provided by the MCWG and the stakeholders of the project, the capacities of the local stakeholders, and the cost limitations of the TMS project.

1.2 Development of the TMS expert study (Sep 08 - Oct 09) During the development of the TMS expert study, a thematic working group was established for discussing the methodology proposed for the monitoring of Aquatic vegetation and Habitats. The thematic working groups met two times in Transboundary Thematic Workshops (Korcha, 20 February 2009; Struga, 15 May 2009), organized and fully supported by the GEF/UNDP Prespa Park project. The thematic working groups consisted of national thematic experts from the three littoral countries. The theme “Aquatic vegetation and Habitats” was presented at the Transboundary Thematic Workshops, and reviewed by the national thematic experts. They were further circulated by e-mail to the national thematic experts and the MCWG members in the period February-July 2009. The final draft of the consolidated TMS expert study was presented at the fourth MCWG meeting (Bitola, 26 November 2009) including 8 indicators (Table 1). A prioritization of the indicators proposed in each theme was asked in order to match the available budget and to implement phase 4, “the Pilot application of the transboundary monitoring system”.

1.3 Indicators selected in the theme Aquatic Vegetation & Habitats for the pilot application of the TMS A final set of indicators was selected during the fourth MCWG meeting based on a proposal by SPP. The general criteria upon which the present draft proposal has been based were:

Cost limitations of the SPP TMS project Efficiency Availability of other resources (equipment, staff) Institutional maturation Availability of baseline information Capacity of local stakeholders In the theme “Aquatic vegetation and Habitats” two indicators were retained for the pilot phase (Table 1): WV5 Location and surface area of patches of the habitat “Reedbeds” and WV6 Species composition and structure of the vegetation of “Reedbeds”. Indicator WV5 was based on remote sensing classification of vegetation habitats. As this classification was not retained for the pilot phase, SPP proposed to produce from satellite pictures one reedbed map for the whole catchment. Proposed institutions: the following institutions have been identified as potentially involved in the monitoring of Aquatic Vegetation and Habitats:

Albania: Museum of Natural Sciences, Tirana (MNS); University of Tirana Former Yugoslav Republic of Macedonia: Biological Institute of the Faculty of Sciences and Mathematics of Skopje; Hydrobiological Institute of Ohrid Greece: Society for the Protection of Prespa (SPP); University of Patras; Other universities & technological education institutes Timetable: The period for the pilot phase for the reedbed indicators was defined as ideally in the months June or July. Provisional Budget: € 8,500 (SPP) Proposed co-funding: Equipment (1 GPS for each team/ country; 250€ each)

3. Implementation and results of the pilot application of the Aquatic vegetation and habitats monitoring for the TMS 3.1 Preparatory phase Spreadsheets Two protocols were defined, one for helping classification of wetland habitat and testing the results, the second for monitoring the structure and species composition of the reedbeds. Spreadsheets were prepared for each of these protocols.

Selection of transects SPP provided a map of reedbeds established on the basis of satellite images1, GoogleEarth images and field verification by SPP staff (Annex 1). The protocol developed for the monitoring of the reedbeds indicated 20 transects in reedbeds to be distributed between the 2 lakes and the 3 countries. A preliminary GIS analysis of the maps allowed us to measure the surface area, perimeter and fragmentation index for each patch of reedbed (Annex 2) and thus the total surface area of reedbeds in each country and in each lake (Table 2). The number of transects to be made in each country and each lake was calculated as a function of its contribution to the total surface area of reedbeds in the transboundary park. The total surface area of reedbeds was estimated at 2265ha among which 53% in Micro Prespa. Greece and Former Yugoslav Republic of Macedonia share about the same surface area of reedbed (close to 40%, while Albania encloses only 20% of the reedbeds of the Transboundary Park. These values are rough estimates considering the method used for delineation. The resulting number of transects is almost equal in the 2 lakes, respectively 9 transects in Macro and 11 transects in Micro Prespa with 4 transects only in Albania and 8 transects respectively in Former Yugoslav Republic of Macedonia and in Greece (Table 2). A random selection of transects was prepared before field work. A number of random points at the outer (dry) edge of the reedbeds were identified in each country and lake. These points were potential starting points of transects, their direction being along the main slope of the shore. The transects were then selected from a random selection among these points (Table 3, Annex 1).

3.2 Implementation The protocols were tested in the field and discussed in the 3 countries. On the first day (June 30th 2010), the history of the process, the description of the protocols and the agenda for the 3 days were reviewed during a joint meeting gathering all groups (Zagradec, Albania). It was also repeated that each country had the responsibility of implementing the protocols and established that the data should be sent to P. Grillas for a synthesis. The 2 protocols were tested in the field in the three countries. The water level of the lakes was relatively high on that date (854.50 m in Micro Prespa and 844.75 in Macro Prespa according to measurements done by the SPP) resulting in all reedbeds being flooded. Boats were thus needed for most sampling stations.

Characterization (Location and surface area) of reedbeds The protocol was tested in seven locations in Micro (3) and Macro Prespa (4) in all countries (Table 4 and see data sheets in Annex 3). Only minor modifications were suggested on the spreadsheets, removing useless information and adding some place for noting coordinates of the edge of the reedbed. Beyond the formal testing in the field, the implementation of this protocol needs to be reconsidered in the perspective of the selection of indicators. The indicator “Location and surface area of reedbeds” was defined in combination with remote sensing classification of vegetation. The protocol included 60 points, half of them being devoted to helping classification and the other half aiming at testing the results of the classification. As the remote sensing classification of vegetation is not implemented, the rationale of the selection of the points has weakened. It is however recommended to maintain this protocol aiming at the characterization of the reedbeds in at least 60 points distributed in a wide range of situations (depth, geographical location, …) and of structure of the reedbed (height, density, species composition). The rationale for maintaining the protocol is that it is very likely that in the following years satellite data will be available at lower cost, thus allowing using the field data for improving the identification of reedbeds. In addition to the 60 points made in reedbeds, it is further recommended to locate points at the edges of the reedbed that will be very useful for improving the satellite delineation of this type of habitat. A revised version of the spreadsheet for the characterization of reedbeds is provided in Annex 3.

Species composition and structure of the vegetation of reedbeds The protocol was implemented with 1 transect in Albania (Micro Prespa), 2 transects in the Former Yugoslav Republic of Macedonia and 1 transect in Greece (Macro). The field testing of the protocol led to only minor changes on the spreadsheet to facilitate field

11


work (the revised version of the spreadsheet is given in Annex 4). More significant adaptations were needed in the implementation of the protocol; these changes had two aims: (1) decreasing the time spent in moving with difficulties within the reedbeds (especially when water level is high) (2) increase the surface area of the sample in order to get a better description of the vegetation and (3) focusing the monitoring on the largest reedbeds. The use of a rake is recommended for the inventory of submerged vegetation of the quadrats, as it appeared that this type of aquatic vegetation is abundant in specific sites (e.g. Micro Prespa, Albania).

Location of transects and quadrats The protocol was based on a random selection of transects and the systematic distribution of 5 stations (4x4m) along the transects. The transects were identified by a random starting point to be found with a GPS (see above: 3.1 Preparatory phase). In late June 2010 the high water levels combined with a high density of reedbeds increased the difficulties to reach precisely the starting point of the transects and the quadrats. To reach the starting point would have been relatively easy in dry conditions but moving the heavy fisherman’s boat in the dense reedbed proved very difficult. It is thus recommended to use a light boat (e.g. canoe) in dense reedbeds. Similarly, the transect can be established from the inner (deep) side of the reedbed to the dry/shallower part when access is from the open water. A random point is selected at the inner edge of the reedbed (approximately at the end of the transect planned in preparatory work) and a compass direction towards the shore (shortest distance to the shore) is identified. The starting point of the transect on the shore is then identified and marked with poles. Beyond difficulties of movement within the reedbed, in flooded conditions the quadrats cannot easily be marked with poles. It is thus recommended to evenly distribute the quadrats along the transects. This can be easily made with the GPS. The number of quadrats can be adjusted to the length of the transect, considering that the distance between 2 successive quadrats should be at least 30m and that the quadrats should be located at least at 20m from the edge of the reedbed.

Size of the quadrats The 4x4m quadrats were considered too small regarding the patchiness of the vegetation. Quadrats 5x5m are recommended.

12


Summary of changes It is recommended to use a light and narrow boat (canoe) for sampling. If not available and the starting point is difficult to reach, the transect can be moved slightly if (1) located less than 200m from the initially identified random transect, (2) there is no evidence of differences within the reedbed. The quadrats do not need to be individually marked because of difficulties in access and inserting poles from a light boat. Use of a rake for sampling submerged vegetation. The size of the quadrats is established at 5x5m.

Size of the reedbeds The reedbeds fulfill different functions in ecosystems among which the most important are probably habitat for wildlife and trapping nutrients, thus reducing the risk of eutrophication. Although narrow strips of reedbeds can play an important functional role limiting in the nutrient input into the lake, the surface area of reedbeds is important for the functions it fulfills, especially for wildlife and the breeding birds. Considering the extensive distribution of small reedbeds in Macro Prespa (28 patches and 966 ha cumulated surface area, Table 4) and the limited number of transects used for monitoring, it is considered that these transects should be better located in the 13 patches of reedbeds which cover at least 15ha surface area. The cumulated surface area of the reedbeds larger than 15ha represents more than 92% of the total surface area of reedbeds in Macro Prespa (Table 4).

Two transects are located in reedbed patches of very small size in Macro Prespa: in patch 24 (transect 4) and in patch 4 (transect 7). These 2 transects have been replaced in the final table by 2 random transects: n° 16 in patch 9 and n° 10 in patch 20. The final list of transects in Macro Prespa is thus given in Table 5.

3.3 Conclusions The field test demonstrated the suitability of the proposed protocols, requiring however some changes in order to improve efficiency (data collected in the field are in Annex 5). To move and establish precise transects and quadrats in the reedbed proved difficult, especially with the relatively high water levels met in 2010. Therefore, the need to mark the transects and quadrats is less and the use of the GPS is sufficient for approximate location. The protocol for the characterization of the reedbeds is restricted by the non availability of remote sensing analysis. Thus, the field results cannot be used for validating the delineation and classification of the reedbeds. It is recommended that resources and opportunities are sought for land use and vegetation maps using remote sensing. It is also recommended to implement both protocols at least every five years (three would be better) in order to store historical data on location and species composition of reedbeds. The implementation of the protocols in Macro Prespa requires significant travelling. Considering on the one hand the limited resources, and on the second hand the

15


distribution of reedbeds in Marco Prespa, the selection of reedbeds has been revised in order to focus on the largest patches with higher conservation interest. Thus, emphasis should be given to the reedbeds located on the northern lakeshore, i.e. those of Ezerani Nature Reserve. Field visits showed important submerged macrophytes beds in Micro Prespa in Albania. An inventory of the submerged vegetation in both lakes is recommended.
