| 1 | Hajnówka, Wilczy Jar | 416Ad, 416Cf; N 52°70’, E 23°65’ | Progeny of autochthonous silver fir from the Tisovik reserve (the Belarusian part of the Białowieża Forest) growing in a half-sibs plantation in the amount of 1,918 trees and aged 31–34 years (in 2026). The plantation is fenced and consists of three plots of 0.22 ha each. Trees in all plots are in excellent condition. The second and third plots showed an increased mortality in the first years after planting, which was due to the influence of late spring frosts. The stand is registered in the European database of important genetic conservation sites. |
| 2 | Białowieża, Podcerkiew | 520Ac N 52°67’, E 23°70’ | The forest cultures from seedlings of autochthonous silver fir from the Tisovik reserve, age 30 years (in 2026). Four unfenced plots with a total area of 0.83 ha were heavily damaged by animals. Planting material for these cultures was produced in the former nursery of the Białowieża Forest Enterprise. |
| 3 | Browsk, Jelonka | 121Dh N 52°80’, E 23°69’ | Progeny trial established in 1997 from seeds collected in the Białowieża Forest Enterprise, Stoczek Forest District, subcompartment 453Al (see stand 6 below). It is not fenced and, therefore, heavily damaged by animals. |
| 4 | Białowieża, Batorówka | 469Ad N 52°69’, E 23°72’ | A forest plantation, 19 years old (in 2026). Planting material – 3-year-old seedlings from the Goldap Forest Enterprise. Seeds collected from trees in Makówka Forest District, subcompartment 177c; origin – probably Germany. Planted on the fenced territory of the former forest nursery; area 1.4 ha; initial planting density 5,700 seedlings/ha. Needs to be cleaned up. |
| 5 | Białowieża, Stoczek | 500Cd N 52°67’, E 23°84’ | A group of 11 old trees at the age about 100 years heavily damaged in their youth by animals. The undergrowth is also badly damaged by animals. |
| 6 | Białowieża, Stoczek | 453Al N 52°70’, E 23°89’ | A group of 93 old trees at the age about 100 years covering area of 0.38 ha. The fenced stand is in excellent condition as is the undergrowth. |
| 7 | Browsk, Jelonka | 156Aa, 156Ba N 52°79’, E 23°77’ | Two old trees in good condition, approximately 100 years old, the potential seed dispersal area has recently been fenced off. |
| 8 | Browsk, Jelonka | 156Ba N 52°79’, E 23°77’ | One old tree at the age about 100 years, in average condition, the seeding area is not fenced, and there is no natural regeneration. |
| 9 | Browsk, Krynica | 769Ac N 52°88’, E 23°63’ | An unfenced group of five old trees at the age about 100 years. Animal-damaged trees are significantly stunted, and there is no natural regeneration observed. |
| 10 | Białowieża, Grudki | 499Ch N 52°67’, E 23°83’ | An unfenced two old trees at the age about 100 years. One of them was significantly stunted due to animal damage. The second one is still in excellent condition, but it is tilted by the wind and apparently has a torn root system. There is no natural regeneration. |
| 11 | Białowieża, Grudki | 526 Bd N 52°67’, E 23°82’ | A group of 40 old trees at the age about 100 years, scattered over an area of 6.39 ha, not enclosed by a fence. Trees undamaged in youth by animals now show excellent growth rates. Natural regeneration is represented by single specimens, which are severely damaged by animals. One tree in this group showed the best growth performance in Białowieża Forest: H = 33m, DBH = 71 cm, V = 7,11m3. |
| 12 | Białowieża, Grudki | 498 Ci N 52°67’, E 23°81’ | A fenced group of 30 old trees at the age about 100 years spread over an area of 1.4 ha. Natural regeneration due to damage to the fence was injured earlier by animals, but it is now in good condition and its population reaches 13.85 pcs/ha. |
| 13 | Białowieża, Stoczek | 452 Bh N 52°70’, E 23°89’ | Seven old trees at the age about 100 years in a quite good condition, arranged in a compact group. Natural regeneration is represented by single specimens, which are severely damaged by animals. |
