On 28th Septeber and 4th October 453 trees were surveyed and defined in the Raina park.
Height, diameter and vitality of these trees were measured. GIS Specialist remained
coordinates.
In the Raina Park 46 trees and shrub taxa have been defined (species, subspecies, varieties,
forms and grades), including 14 autochthonous (local) species, as well as 32 alohtona (alien)
trees and shrubs taxa (species, varieties and genuines).

The most of the Raina park's greenery form local wood taxa: small-leaved Lime (Tilia
cordata) - 28%, the average vitality -1.8; Norway maple (Acer platanoides) - 11%, the
average vitality - 2.4, English oak (Quercus robur ) - 8%, the average vitality - 1.6, silver
birch (Betula pendula) - 7%, the average vitality - 2.3, downy birch (Betula pubescens) - 7%,
the average vitality - 2.2; ash (Fraxinus excelsior) - 6%, the average vitality – 3. Percentage
of the alien trees in the park greenery is less than three %.

As new, inappropriate for planting (vitality level - 6) were evaluated: Juniperus sabina,
Juniperus squamata 'Meyeri' and Salix alba genuine. The Japanese azalea (Rhododendron
japonicum) and horse chestnut (Aesculus hippocastanum) plants with vitality 6. These plants
had also gained varying degrees of frost damage, so objective assessment of landscape plant
capacity during the inventory was not possible.
Fig.2. Tree species distribution according to vitality
For the park plantations the trees and shrubs (Acer negundo, Rosa pimpinellifolia and Spiraea
chamaedryfolia) are used. These species for Latvia are defined as invasive and can go wild
and degrade local ecosystems. In areas where these species are planted, additional monitoring
is required, upon necessity - management activities.
Especially valuable local and alien trees and shrubs in the park taxa represented only by
Flowering Crabapple (Malus cerasifera, No. 341), whose vitality - is 1 (tree vital, decorative).
In the Raina did trees - natural monuments of the national importance were not found (LR
CM Regulations No. 415 "General regulations on protection and used of specially protected
nature territories„).

Opinion
on the protected plant species found in the Raina park in Rezekne.
The area was surveyed on 28th September and 4th October.
The park is located in the city of Rezekne, 29a Raiņa street. The total Raina park covers area
- 31,426 m2. Within the framework of "GreenMan" project area of inventory in the Raina
park is 6,332 m2 (at children's recreation area), where the park's inventory and protected
species were surveyed.
Surveyed area has been historically shaped by human - sown lawn. In this territory the large
variety of wild plant species is not present. Most commonly found: common dandelion
(Taraxacum officinale), cock's-foot grasses (Dactylis glomerata), cow parsley (Anthriscus
sylvestris), ground elder (Aegopodium podagraria), Common Knotgrass (Polygonum
aviculare), shepherd's-purse (Capsella bursa-pastoris), Timothy-grass (Phleum pratense),
Common Silverweed (Potentilla anserina), mugwort (Artemisia vulgaris), red clover
(Trifolium pratense), chamomile (also spelled camomile ) (Matricaria recutita, Matricaria
chamomilla), white clover (Trifolium repens).
In the areas where the ground is planned to be transformated, as well as in its close proximity
no especially protected plant species were detected (LR MK CM regulation No. 396 of 14
November 2000 „Regulation on the species list of especially protected species and of species
of limited use").
In the areas where the ground is planned to be transformated no specially protected habitats
were noted (LR CM regulation No. 421 "List of specially protected habitats").
In the areas where the ground is planned to be transformated, no plant species and habitats
from the European Council Directive 92/94/EEC of 21 May 1992 „On the conservation of the
natural habitats and of the wild fauna and flora” were found.
Conclusion: No especially protected species and habitats will be destroyed as a result of
transformation of the Raina park territory of ( 6,332 m2) in Rezekne.
To rate vitality of woody plant on 6 - point scale
1. Vital, ornamental tree management measures are not provided.
2. Vital tree, immediate management measures are not provided. Trimming of dead branches
or care of tree crown is possible in the future.
3. Average tree vitality. The tree has no outstanding landscape value. It requires care of
crown, cutting of dry, cracked branches and things. Caring for the tree crown is required, in
order to extend landscape value of the tree.
4. Weak tree vitality. The tree is crushed, with a deformed crown. Emergency tree cutting is
not necessary, but in order to maintain a long-term view and a model for the park - a tree can
not be saved.
5. Tree vitality is weak or dead tree. The tree has completely lost its landscape value. It can
not be saved in the park and, if necessary, should be replaced with new seedlings.
6. The vitality of trees can not be established.
