In fact, its belong to the soil-like bodies such bodies that are not related to soils, with some specific properties for them, perform functions or occupy the space, usually belonging soils. Soil ecosystem services approach can help us to know which profits can we receive from the soils of the Pechurki quarry. Using only the significant variables issued from the forward selection, we then performed a canonical correspondence analysis CCA to determine how those environmental variables influenced the distribution of the plant communities previouslu identified.
Press "read more" to learn more about this analysis. Currently, the quarry is closed to the public as it is being prepared for reclamation. After reclamation and once it is re-opened, the number of ecosystem services quarry will increase significantly, as well as it is value. However, even now it carries a huge range of ecosystem services. We estimated the value of the ecosystem services provided by the plant communities in the quarry. We evaluated a large number of physical and chemical soil parameters. To improve the quality of the model and further analysis, it is necessary to choose the factors having the greatest impact on the vegetation.
Reducing the number of variables was performed by the forward selection method. The most important factors were the pH, soil texture, proportion of fine particles in the soil, humidity, stoniness. We conducted an inventory of the flora in all quarry. Recall that all we found species of vascular plants. Floristic analysis showed us some interesting results. Our project is aimed not only to reach scientific people, but also to introduce biodiversity of the quarries for children and non-scientific people.
Time goes by and we began to discuss our final report. As we said in our quarry several phytocenoses found its place. We summarize the educational part of the project. More than 1, children have learned about our quarry and biodiversity, and we promise to continue their studies after the completion of the project.
Important in creating lessons was that the children themselves have sought to seek knowledge. We are accustomed to the fact that a wide variety of community and high productivity, indicate the favorable condition of the ecosystem. Is it always so? In order to mitigate the effects of climate change the atmospheric removal of greenhouse gases is necessary. Restoring degraded soils and ecosystems has a high potential for sequestrating soil C.
The strategy of soil C sequestration is cost-effective and validated in sense on sustainability. Reclamation strategies should be based on our knowledge of the main ecological factors of plant establishment and effects of organic matter accumulation in soil deponation of CO2 in pedosphere.
Do you Today we want to introduce you typical soil profile, which was describe during our work on the Pechirki quarry. We also continue to study Red Book species of plants that we found on the Pechurki quarry. We are continue to introduce you the results of our work on studying of soil cover on the Quarry. And we are happy to take part in it and tell about our finds from the Pechurki quarry. We investigated the long-therm effects on biodiversity and economic advantages of some restoration approaches at the Pechurki quarry, included tree planting and spontaneous succession.
Our results highlighted that spontaneous succession is the best way in terms of cost and it ensured higher species diversity, vegetation structure and greening. Our contest is coming to an end and we started rewarding our young participants. We are trying to give more detailed information about soil diversity of the Pechurki quarry. Once we realised the importance of telling you story of embryozems, their types, their distribution and their natural history. Today we introduce you with a list of species of algae and cyanoprokaryota collected in the quarry Pechurki lake.
Another widespread at the quarry species of ant. The water permeability of the soil was determined on terraced plots of the quarry by the tube method with variable-head. According to the obtained results, value is mm in the first hour, and it corresponds the best permeability according to N. Click "read more" to find out more about water permeability of the soil. All plants from the Red Book for various reasons, are on the verge of extinction, and we can not prevent their destruction. Everyone who met the plants from the Red Book, should help their reproduction, or at least to keep in pristine condition.
We got the primary results of the species composition of the algae and cyanoprokaryota in the lake of the Pechurki quarry. Ecosystem services are the functions of the ecosystem that in some way benefit mankind. As we showed earlier, abandoned quarry - it is not a useless land, quarry is the source of a number of ecosystem services, and we decided to evaluate which ones. Black garden ant - Western Palearctic species of ants. Something new about the main soil type which was indicated on the Pechurki quarry.
Today we will discuss evolution of embryozems in space and time. Today, we continue to acquaint you with protected species of plants, which we found on the Pechurki quarry. Today we tell you about small-leaved forests in the Pechurki quarry. Dear friends! Look at this photos, this community have the same number of species and the same value of the Simpson index. But this communities differ! Biodiversity may be hidden and the best proof of this is the existence of different life forms of plants.
So, do you know what we have found? The first member of the family Orchidaceae which is taken under the protection and included in the Red Book. For the first time in the Leningrad region it was found Anomala dubia! Where do you think? That is, on the Pechurki quarry. We show you a map of plant communities. Accumulative water bodies biotopes are key habitats for the Pechurki quarry. We are continuing to introduce you the results on studying soil cover of the Pechurki quarry. Today you will be familiar with results on analysis of the main soil type of the quarry - embriozems.
Everyone knows that revegetation of quarries is process of primary succession.
Structure of Plant Diversity
Visibly plant communities are not fixed forever, but seem to be constantly changing. Earlier we have presented the results of the different diversity measures for those plots, where there is vegetation cover. It is time to sum up! How biodiversity changes in space? We have made a presentation in the international volunteer camp "Ecological Raids" we were talking about quarries and rehabilitation.
What do you know about ants living in the Pechurki quarry or we have identified the next species of ant. Many scientists believe that he Berger—Parker index is a practical and effective tool for monitoring biodiversity impairment linked to human disturbance in ecosystems. That is why we have decided to to calculate it. The Shannon diversity index H is another index that is commonly used to characterize species diversity in a community. Like Simpson's index, Shannon's index accounts for both abundance and evenness of the species present. Today we discuss about some of the most interesting and harsh conditions for the development of plants in the quarry Pechurky.
We have obtained the results about electrical resistivity in soils of studied areas on the Pechurki quarry. Species richness S is the simplest measure of biodiversity and is simply a count of the number of different species in a given area. This measure is strongly depended on sampling size and effort. It is just funny video of our meeting with Zootoca vivipara in the quarry.
Dear friends, do you know that the sites that have the same number of species may have completely different levels of biodiversity? The fact is that in addition to the number of species it is important to take into account its abundance. Today we present you the results of Simpson's diversity index of different parts of the quarry. We want to introduse you to a quarry biotop. Dry pine. The photo shows one of the representatives of soil covers - Peltigera didactyla. We have already started talking about the fact that different types of relief have completely different species composition.
But who wouldn't want to evaluate to what extent. For this purpose, we calculated the coefficient of Sorensen-Czekanowski. As we promised, we share with you the video of the insects collecting method. Good news: on the international scientific conference in in Sukhum Abkhazia await our report about diversity of plants in the Pechurki quarry. This is an excellent opportunity to present and discuss our results because many authoritative researchers and practitioners will be there.
One of the methods to characterize community is just count the member of species. Let's know which sites of quarry have more species of high plants and in some less. As you remember, we have performed large number of classes conducted for children of Saint Petersburg. And now we are ready to share them with you! Our team not only have organized a photo exhibition and a lesson for children in Slantsy.
We also organized a press conference for the residents, the meeting was attended by representatives of radio, television and newspapers! Also, we are organising a tour to the quarry for children. We hope that soon the high natural value of the Pechurki quarry will know everyone! Today we were at the quarry for collecting insects and go through the untouched forest.
Today is a great day for our team! As part of a summer internship in Nizhne-Svirsky State Nature Reserve, lectures Pehurki quarry biodiversity have been carried out. We continue to acquaint you with the diversity of algae in the quarry. For which animal all of these items fit?
Who is a highly developed social animal? Who has great influence on the processes of pedogenesis, and even on the formation of vegetation? Who has reached high results in horticulture and cultivation of mushrooms? Those who have all types of organization of the political regime? And some of them even slaveholders! Many years ago, there was a variety of living organisms in marine waters.
Skeletal remains of these organisms form a rock - limestone. Nowadays, people began to actively produce and use limestone for construction purposes. Since the school we are familiar with the processes of rocks formation. As a result of our research, we have known a lot about the mining of limestone and recovery areas. As common man, we know that is cement. Today we have met with the missing link - we saw all the way stone We promiced you we would share news everyday, but sometimes our team has no internet access.
Nevertheless, we are again with internet connection and will share our news with you 24 hours per day. Today we share with you our preliminary results about the differences in plant communities. Diatoms are a next common algae type. Now we are in the process of determining of humus composition of the soil. First, let us tell you what does humus mean. You can actually see how we found a rare species of orchid. The main dominants in the species composition of algae on the quarry are diatoms and blue-green algae. We used clustering analysis to compare the plant communities that colonized different ecotopes of quarry.
Let's see what's under the tree on the hill. We have found the quarry endangered species Dactylorhiza maculata, which is included in the Red Data Book of the Leningrad region. Today, we determined the hygroscopic moisture content of our soils. More detail study vegetation biodiversity of quarry. We have measured CO2 content of carbonates in soils of the quarry.
It need for accurately predict future CO2 levels in the atmosphere, which is crucial in predicting global climate change. According to the results carbonate content in soils of the quarry is low. That means there is a potential atmosphere CO2 sink from Pechurki quarry is little. We have started identify the composition of algae from the Pechurki quarry. The main idea - the variety of life in one drop is much higher than we think.
The main objective of our last trip was to study the vegetation biodiversity. The main news of the day is, that we went to the quarry again. Diversity of soils in the quarry is great.
We begin with grey-humus embryozem your acquaintance with them. You need to have a magnifying glass in order to determine the diversity of species in the quarry. And you can see the wonderful world of crustose lichens. What we can do on a Friday night in the country? Certainly our project. Today our team took a real debate. We were talking about the success of reclamation and realized that everyone understands it differently.
We have identified soil texture and soil structure at the different sites of quarry. Soil texture and soil structure are both unique properties of the soil that will have a profound effect on the behavior of soils, such as water holding capacity, nutrient retention and supply, drainage, and nutrient leaching.

The vast majority of soil samples are optimal for plants. There are, however, exceptions. We have identified diversity of moss on the quarry. But firstly let is see what does it is for. They are ecologically important for many different reasons. They help retain water and humidity, fertilize and stabilize the soil, control flooding, and provide shade and shelter for insects and small animals.
Mosses help replenish the earth's acid and nitrogen levels. These are the main causes for search moss, to understand its diversity and finally, above all, to preserve it. On the quarry we have Our team is full of enthusiasm about the future. But we realise that we have to work hard in order to be successful in our project.
Our team is continuing to check the work of children and we try to highlight the best of them, but it is very difficult. Oksana Kuznetsova received first degree diploma for the report at the conference "Ecogeology ". We continue to share with you the best essay about quarry. This story was written by Stolyarova Anastasia. We came back from the quarry with new soil samples, which have to be treated. One of the best essay about quarry was written by Kalinina Sofiya. And it's not just an essay. One part of the fairy tale is even written as a poem!
During the holidays, we continue to conduct educational part of our project in the children's school camps. He will help us to determine of genetic material recovered directly from environmental samples from our quarry and to assess levels of microbial diversity. We were on quarry again! This method was first adopted in geology by oil companies searching for petroleum reservoirs and delineating geological formations.
Only today and only now you can immerse yourself in the determination of particle size distribution of our wonderful career. Cyanobacteria or blue-green algae are the active agents of biodegradation of limestone in the early stages. Studying of their composition will allow us to describe the primary processes soil formation and the formation of fine earth. Tomorrow's leaders need to be equipped for tomorrow's challenges, and we must adequately prepare our children for the future they will inherit.
That requires a commitment to providing children with environmental education that helps them become the educated thought leaders of tomorrow. We observed that, based on the prevailing conditions, the bryophytes and lichens could potentially act as nurse species and could initiate the restoration of pits! We continue to participate in scientific competitions successfully. This time it was the All-Russian Olympiad on ecology and nature management. The morphology of the soil - is an external pattern of the soil, which is created as a result of the redistribution of soil products.
Mapping allowed us to evaluate your work visually during the first trip and adjust further action. We are very active and successful now in sense of scientific life! Our team is continuing to reach new heights in science!

We moved from words to action! We have started one of the main soil analyzes - determination of pH. Surrounded by persons sharing our ideas and views we have discussed the current state of affairs and formulated an action plan. Today was a very productive day! We enlisted the help of the interregional environmental alliance and the Municipality of the Leningrad region. In May more than children will know about quarries, impact on the environment and importance of ecosystem restoration. Scientific seminar of biodiversity and climate change was held in Moscow.
Oksana Kuznetsova made a presentation which was associated with diversity of lichens in Pechurki quarry. As a result of abundant and common species were identified. Verrucaria spp. These species cause severe biodeterioration of the substrate surface. The other day scientists from different disciplines attended a department of Applied Ecology workshop where we talked about the research part of our project. We are glad to have colleagues with whom we can discuss our results.
Yesterday was the first day of our field work. We have performed reconnoitring works. Also it was established the plan of future works. HeidelbergCement employees greeted us very warmly and friendly and we want to say them big thanks. Educating people about the need of studying the processes of recovery of quarries is the first stage of our project.
