The main targets of the action:

• To evaluate changes of the birds‘ deaths before and after installation of the practical project measures on the high-voltage electricity power lines.

• Separately observe White Storks' mortality trends before and after installation of the practical project measures on the high-voltage electricity power lines.

EX –ANTE results collected by LOD

• Until 2014 data about birds‘ mortality, caused by collision with overhead high-voltage electricity power lines, were collected only in Kaunas.

• During EX-ANTE activity 16 birds‘ death cases caused by collision with overhead high-voltage electricity power lines were collected by LOD.

EX-ANTE results collected by LITGRID

• In 2014 LITGRID recorded 79 short circuits in their overhead high-voltage electricity power lines across Lithuania.

• After control, 41 cases out of 79 short circuits were identified as caused by birds.

EX-POST results collected by LITGRID in a period 2015-2018 • In 2015 LITGRID recorded 19 short circuits caused by birds, but

only 2 of them were on the lines with installed project measures.

• 2016 - 12 short circuits; 2 on the lines with project measures.

• 2017 - 23 short circuits; 3 on the lines with project measures.

Ex-ante and Ex-post monitoring on the effectiveness of the project conservation actions: Common Kestrel

protection on electricity pylons

Page 23: Birds‘ monitoring within the high voltage dokumentai... · 2018. 7. 3. · voltage electricity transmission grid in Lithuania “ Nr. LIFE13 BIO/LT/001303 Project‘s biological-experts

The main targets of the action:

• To reduce deficit of breeding places for Common Kestrel (Falco tinnunculus) on electricity pylons by installing 580 nesting boxes on electricity grid in Lithuania

• To increase breeding success of Common Kestrel‘s population in Lithuania

Page 24: Birds‘ monitoring within the high voltage dokumentai... · 2018. 7. 3. · voltage electricity transmission grid in Lithuania “ Nr. LIFE13 BIO/LT/001303 Project‘s biological-experts
Page 25: Birds‘ monitoring within the high voltage dokumentai... · 2018. 7. 3. · voltage electricity transmission grid in Lithuania “ Nr. LIFE13 BIO/LT/001303 Project‘s biological-experts

Monitoring before erection of nest boxes

• Survey of occupied nesting boxes of Common Kestrel was made by LOD members covering all Lithuanian territory;

• Questionnaire was sent to the staff of protected areas administrations;

• From collected data maps were produced according registers of breeding territories of Common Kestrel;

• The places to erect nesting boxes were chosen on the electricity grid closer to the breeding areas

Common Kestrel breeding attempts in Lithuania

Page 27: Birds‘ monitoring within the high voltage dokumentai... · 2018. 7. 3. · voltage electricity transmission grid in Lithuania “ Nr. LIFE13 BIO/LT/001303 Project‘s biological-experts

EX -ANTE:

Common Kestrel breeding situation in Lithuania before project actions

• National breeding population was estimated at 150-300 pairs

• Information covers data from 10 past years

• In all territories where nesting boxes were erected, it was a new praxis (never done before)

• Before project Common Kestrel was nesting in various locations: from old corvids nests to cities buildings

• Just before project some attempts to install nesting boxes were made in Western part of Lithuania

• In Western part of Lithuania breeds about 50 % of national Lithuanian population

Page 28: Birds‘ monitoring within the high voltage dokumentai... · 2018. 7. 3. · voltage electricity transmission grid in Lithuania “ Nr. LIFE13 BIO/LT/001303 Project‘s biological-experts

Monitoring of erected nesting boxes includes

• Two parameters are recorded: • Occupation of nesting boxes

• Breeding success

• During monitoring all data are entered to the online data base

• Nesting boxes will be monitored during project duration

• We hope the highest occupancy of nesting boxes will be after 4-5 years after installation.

EX –POST RESULTS

Until breeding season in 2017 for Common Kestrel were erected 475 nesting boxes

After monitoring 74 occupied nesting boxes recorded

Higher breeding success was recorded closer to large

cities and in Western Lithuania

• Klaipėda region on of the key breeding sites for kestrels in Lithuania

• Breeding birds expand their territories based on the erected nesting boxes

EX -ANTE RESULTS:

Breeding success and juveniles‘ numbers

• Totally in 2017 year were occupied 74 nesting boxes, raised minimum 198 juveniles, 2016 respectively 108 juveniles.

• 2017 years were occupied 13,47% of all erected nesting boxes

• Average juveniles number in 2016 - 4,2 per nesting box, in 2017 – 3,5/nest box.

• Totally from the 2015 in nesting boxes raised more than 451 juveniles!
