Macroinvertebrates of two ex-manor ponds located in Chroscina, Opole Region (Poland) were studied from 2015 to 2018 to investigate their community composition and diversity and evaluate the heterogeneity of communities on spatial and temporal scale referring to environmental variables and revitalisation work. A total of 32 taxa were recorded (at the family level, except Oligochaeta), 13 of which were Ephemeroptera, Odonata and Trichoptera, recognised as sensitive groups in lentic ecosystems. Macroinvertebrate richness and diversity varied considerably, especially in spring and summer. It was found that habitat heterogeneity influenced benthic invertebrates more than basic water parameters. However, the environmental variables together accounted for only 38 % of the observed variations. Thus, other factors, such as fish predation, may have played a leading role in community shaping. The distinct differences between pond communities, four years after the revitalisation works, resulted more from different habitat features than from the previous sediment removal.

Manor-house parks are an important part of natural and cultural landscape of Polish countryside. While sites designated as historical do enjoy an elevated “social” status, this does not always translate into its monetary market value. Own research shows large price discrepancies in property appraisal reports for the same real estate. The discrepancies were related to valuation of vegetation (Rosłon-Szeryńska, 2018). Even though there are many methods and techniques of appraisal (including: profit-, market-, cost-oriented or mixed) available in specific legal acts and standards, apprising vegetation is still problematic. The goal of this research is to evaluate reasons behind these glaring discrepancies in appraisal of manor-house and park complexes in rural communes. Research included an analysis of current market prices of 100 historical real estates comprised of a manor-house and a park from all over the country. Regression analysis proves that the share of park’s value in the overall historical real estate price is too low. This particularly applies to parks with an area of less than 5 ha.

In the 20th century Poznań extended its limits and annexed many manor farms surrounding the historical city. At present the residences, parks and gardens which used to be part of manor farms are an element of the city landscape. Some of them still exist but others were degraded. This paper focuses on the condition of historical manor parks and gardens in Poznań, their problems and difficulties and methods of their use and protection in a modern city.

Poznań, poszerzając swoje granice, wchłonął wiele majątków otaczających historyczne miasto. Związane z nimi założenia rezydencjonalno-parkowe w zróżnicowany sposób funkcjonują dzisiaj w przestrzeni i krajobrazie miasta. Część parków i ogrodów podworskich nadal istnieje, inne uległy degradacji. Należy zadać pytanie o ich dzisiejszą kondycję. Zapytać o problemy i możliwości ich wykorzystania, a także ich ochronę we współczesnym mieście.

Manorial estate in Rybieniec has been legally protected since year 1999, when it was included to register of monuments with number 1 7/Wlkp/A. Manor consist of manor house build in 1910 and park from the turn of XlXth and XXth century, with area of 2,7 ha. Manor farm, which were a part of Rybieniec manorial estate is not existing anymore. There is only one non historical, partly demolished building, elevated by PCR (Panstwowe Gospodarstwo Rolne - State agricultural farm). Manor farm was used by PRG after Second World War. All spatial complex is picturesque localized on a slope over lake. Manor hause and park have good landscape exposition from a road leading to Rybieniec, because of high location in terrain. The aim of the studies is to investigate composition of trees and shrubs species and collecting information of historical spatial arrangement of the park. In 2009 garden inventory within dendrological inventory was made, also historical studies were completed. In 2010 project of revalorization of historical park were started. Due to completed studies richness of composition of trees and shrubs species was displayed also historical spatial arrangement of the park and arrangement of historical plantings were identified. Results of studies were used in revalorization project.
