SLIDE 2 The concept of MR in a nutshell (1)
dispersedly breeding species by the designation of small protected areas;
- The main function of MR is
providing of necessary protection arrangements for the nest site/ breeding habitat;
- Buffer zones (BUF) can be
established for providing of additional (seasonal) protection during the breeding season.

Natura 2000 sites and microreserves in Latvia in 2010
Total number of MR: 2095; NCA 2010 (state on 29.12.2010)
SLIDE 4
Bird microreserves in Latvia in 2010
Number of bird MR’s in 2011: 1184 (57% from total) with a total area of 33 876 ha, SFS (state on 19.08.2011)
SLIDE 5 The concept of MR in a nutshell (2)
- First MR established in 1973, since 1978 - on more regular basis;
- Initially radius around the nest used as a size parameter (now –
maximum area in hectares);
- Initially duration period was set at 3, later - 10 years (now – not
termined);
- System has been developed further by introducing of Buffer zones
(BUF) – (2001) provide additional (seasonal) protection during the breeding season;
- The initial list of species has been widened and now this concept is
used for protection of other groups (mammals, birds, fish, reptiles, amphibians, invertebrates, vascular plants, ferns, mosses, lichens, fungi and algae) and protected habitats as well;
- Concept of “patchy microreserves” developed in 2009.

designed as a solid uniform areas, encircled by the BUF;
fragmented forest landscape:
areas of young stands, not suitable for breeding of particular species;
the conservationists and forest owners
“Solid” microreserves
SLIDE 9
“Patchy” microreserves
In breeding territories where pairs are moving between several subcompartments, protected territories are created in each of those areas, considering potential further resettlings; Microreserves are created using “patchy approach” – only stands potentially suitable as a breeding grounds are included, younger stands included in the buffer zone
MR: 40,3 ha BUF: 70,0 ha MR: 32,1 ha BUF: 130,3 ha

SLIDE 11
- Advantages:
- Better using of maximum allowed MR territory through the better
shaping of area;
- Stands, not suitable for breeding excluded – easier to argument;
- Shortages:
- Modelling of future resettling directions not always successful,
“patchy” MR could be the same abandoned through the resettlings;
“Patchy” microreserves: “+” and “-”
