Adaptive community-based management of urban biodiversity for enhanced ecosystem connectivity and health

The global decline in biodiversity has highlighted the need to focus more on urban areas. Cities increasingly serve as refuges for wild plants, as conserving species solely in protected areas is insufficient. Additionally, nature-based solutions are gaining importance for adapting to changes brought about by the climate crisis. Urban green spaces also play a crucial role in promoting citizens’ well-being and physical and mental health and can serve as venues for community gatherings and social integration. All these aspects are encompassed in the “Urban Meadows” initiative within the urbanLIFEcircles project.

Since 2021, the Latvian Fund for Nature has been establishing Urban Meadows in Riga and other cities. This project, and the LFN’s involvement in it, represent a natural extension and expansion of our ongoing efforts to preserve biodiversity.

Project Number: 101074453 – LIFE21-NAT-EE-urbanLIFEcircles

Project Duration: 16.09.2022 – 15.09.2027

Locations: Latvia, Estonia, Denmark

Project Manager: Riia Ränisoo, City of Tartu

Project Manager at the Latvian Fund for Nature: Nora Rustanoviča

What is an Urban Meadow?

An urban meadow is a grassland dominated by native perennial wild plants and managed to enhance the biodiversity in the city.

Our goal is to create at least 45 urban meadow areas totalling at least 15 hectares by 2027.

How Did Riga’s Urban Meadows Originate?

At a time when natural grasslands and other habitats are in rapid decline, cities are playing an increasingly important role in conserving biodiversity by becoming places of refuge for wild plants and animals.

The author and promoter of the idea of the urban meadows in Riga is Rūta Sniedze-Kretalova, botanist at the Latvian Fund for Nature (LFN). The first urban meadow areas were created in 2021 with the support of Riga City Council and project GrassLIFE implemented by LFN. Since then, urban meadows in Riga have been created in project urbanLIFEcircles by the LFN in cooperation with Riga City Council and local citizen communities. Local citizen communities suggest areas of grassland owned and regularly managed by the municipality that they would like to turn into urban meadows instead of their usual lawns. Every year in autumn, local residents take part in urban meadow creation events and help monitor these areas, reporting their observations to LFN.

Currently, the urban meadow network includes 42 sites covering a total of 13.7 ha. Urban meadows have been established in Jugla, Mežaparks, Purvciems, Ķengarags, Grīziņkalns, Āgenskalns and many other places in Riga.

Why Create Urban Meadows?

  • Wild plants

Urban meadows are planted with native meadow plants, which are essential for restoring and maintaining a healthy ecosystem. Plants attract and feed many other living organisms – soil microorganisms, fungi, earthworms, bacteria, invertebrates, birds, mammals, etc. The greater the diversity of plants, the more life there is in urban meadows!

  • Pollinators

The more plants in urban meadows, the more pollinators! They also work in urban gardens, pollinating crops and increasing the fruit yield in our gardens.

  • Healthy soil

Plant diversity, which attracts a wide variety of soil microorganisms, is the basis for healthy soil.

  • Cleaner air, rain and flood water intake and treatment

Plants filter the air by taking in carbon dioxide in the atmosphere and fixing it in plants, roots and soil. The soil and root system of meadows act like a sponge, capturing and purifying rainwater.

  • Temperature control

Heat islands – places where temperatures are consistently higher than outside cities – are a growing problem in cities. Green spaces, including urban meadows, and the presence of plants cool and make the environment more pleasant.

  • Education

Urban meadows provide an opportunity to learn about ecological processes, as well as the plants and animals they support. It’s a fascinating way to connect with nature!

  • Lower site management costs

Urban meadows should only be mown once or twice a season, saving site management costs.

How Do We Create Urban Meadows?

  1. Site Assesement:Following recommendations from the municipality and the public, we survey potential sites to assess their current condition and suitability for an urban meadow;
  2. Management Planning: We prepare a management plan for each area, providing recommendations for mowing and caring for the area to make it a place rich in plants. At the same time, we contact Riga Forests Ltd and other relevant institutions to implement the management
  3. Ongoing Assessment: We continuously assess the success of urban meadows – identifying and inventory plants and studying the ecological, landscape and social contribution of the ecosystem;
  4. Community Involvement: Together with volunteers, we provide seeds of native wild plants, establish and maintain the urban meadows;
  5. Urban Meadow Creation Events: Every autumn, we expand our urban meadow network by organising urban meadow creation events with various associations and volunteers. We usually approach the neighborhood association according to the location of the site, but everyone is welcome to participate!

How Are Urban Meadow Creation Events Organised?

  • Urban meadow creation events are a collective process where we rake the soil and sow wildflower seeds;
  • These events take place every year in October and November, which is the best time for sowing wild flower seeds, as it is the end of the active vegetation and many plants need cold conditions for seed germination. Also, various seed-eating insects become less active during this period, which means less seed loss;
  • Each urban meadow event lasts approximately about a couple of hours. During this time, participants level the soil with rakes, remove turf, and sow wild plant seeds.

How Are Urban Meadows Evolving?

As ecosystems, meadows evolve slowly and gradually. After sowing seeds, only a few plants germinate in the first year. Most perennial plants develop a root system in the first year of their life, which they use to absorb nutrients and water. This is why we may not see flowers in the first year, as only the rosettes of leaves are formed. In the second or third year of life, meadow plants are mature enough to start flowering and producing seeds. However, not all plants follow this pattern; for example, orchids bloom only several years after germination

The development of urban meadows is influenced by the history of the specific area. If the site has low fertility soils and special topography or moisture conditions, the meadows develop well and the diversity of plant species increases rapidly. Such meadows can be found at the foot of Dreiliņkalns, on the Jugla promenade, near Imantas Market, on Liedes Street, on Jūrmalas Avenue near the Botanical Garden of the University of Latvia and elsewhere.

However, if the soil is too fertile and the site has been mown frequently in previous years, existing plants such as sickle Medick (Medicago falcata), perennial Rye-grass (Lolium perenne) and red Clover (Trifolium pratense) are strong and prevent the seeded plants from developing successfully. However, even if plant diversity is slower to develop, these areas are important for pollinators, provide food and shelter for animals, and provide valuable ecosystem services.

The Most Typical Urban Meadow Plants in Riga

Wild carrot Daucus carota

Wild carrot thrives in most urban meadow areas. The garden carrot has been bred from this species, encouraging the development of a succulent root part. The wild carrot also has a strong, fragrant root, but is too woody to be edible. The wild carrot flowers gradually and its flowers, pollen and nectar are very popular with insects. If you look closely, you can sometimes see a darker coloured spot in the wild carrot flower that looks like a small insect. It is an evolutionary trick! This is how the plant attracts insects, saying: “See, it is so nice here and someone is already feasting!”

Oxeye daisy Leucanthemum vulgare

The oxeye daisy is also popularly known as the daisy. Did you know that this is the national plant of Latvia? The pipe is also one of the most typical Midsummer herbs. The densest stands of oxeye daisy in the Latvian landscape can be found in the oldest fallow land, but it has also become very well established in urban meadows.

Yellow Chamomile Anthemis tinctoria

The yellow chamomile is visually very similar to the oxeye daisy, but yellow throughout. The yellow chamomile are now more commonly seen in dry, gravelly meadows and roadsides, and the urban environment is not so different from the species’ natural habitat.

Yellow Rattle Rhinanthus sp.

Rattleweed are also known as meadow makers. Unlike most other meadow plants, rattleweed are annual and fast growing plants. They flower and set seed in their first year. The rattling of the seeds in their knobs told our ancestors that the time for harvesting the meadows was at hand.

Brown Knapweed Centaurea jacea

The flower of this gorgeous flowering plant resembles a cornflower, which is not surprising as the two are close relatives! However, brown knapweed are typical meadow plants, while cornflower is a field weed. If you look closely, you will see that there are four different species of knapweed in the urban meadows – each with a slightly different flower and leaf shape.

Common Yarrow Achillea millefolium

Common yarrow can be found in all urban meadows, despite the fact that it is not specially sown. The common yarrow is a highly plastic species that can also withstand adverse environmental conditions such as desiccation, soil disturbance and heating. The plant reproduces successfully by rhizomes. Although common yarrow is a common species, it helps the soil to recover from pollution and is a good medicinal plant.

The aim of the urbanLIFEcircles project is to preserve, improve and sustainably manage green infrastructure in cities, increase biodiversity by restoring and improving the connectivity and health of ecosystems, and at the same time provide citizens with new recreational areas to spend time and enjoy the benefits of nature. In the project three cities – Riga (LV), Tartu (EE) and Aarhus (DK) – are united.

The project is implemented in cooperation with the municipality of the city of Riga, Latvian Fund for Nature, the municipality of the city of Tartu and the municipality of the city of Aarhus, as well as several other partners from Estonia. The main activities of the Latvian Fund for Nature are related to the creation and maintenance of HNV-grasslands – city meadows (45 areas) in Riga. City meadows will be created in the lawn areas of the Riga Municipality – wide roadsides, open areas in parks, squares and other suitable places. You can follow the development of the Urban Meadow network on the interactive Urban Meadows map.

Preparing a restoration plan for the HNV meadows in Riga (T.2.5)
  • Through the network of Riga’s Neighbourhood Alliance we will ask citizens’ opinions on which places they want to see as a HNV – grasslands. Riga’s Neighbourhood Alliance is NGO that unites 30 of 38 Riga’s neighbourhood communities with a mission to strengthen their role as important stakeholders in Riga city administration and help communities on the road to a more liveable and sustainable city;
  • We will select the best suitable sites for HNV – grasslands by looking at their plant composition, ecological conditions, landscape assessment, and socio-economic importance (T.2.1);
  • A special restoration and site management plan will be elaborated for each of the 45 HNV sites (T.2.5). The plans will be negotiated with Riga greenery department to guarantee the success of the future implementation after project.
Restoration of the sites (T.3.2)
  • On every site, grass will be mown and removed. In larger, flat places we are planning harrowing soil – to open up by 50% as in most of city lawns soil is heavily compacted. 50 % of bare soil is also recommended before wildflower seeds are sown. In smaller sites, we will use soil aeration, in contaminated places or very eutrophic places we will remove the sod;
  • In every HNV – grassland area we will make an event by creating an urban meadow with the help of local citizen communities. In these events, volunteers will prepare the soil by raking it and removing redundant material and sow the wildflower seeds;
  • Seed material will be collected in various ways – freshly cut grass from good quality EU grassland habitats we use in large places. We will use seed collecting machinery to get seed material for smaller sites. For some special plant species (eg. yellow rattle Rhinanthus minor), we use handpicking;
  • To improve seed germination (in some sites) we will disperse soil from the sites where restoration of EU habitats occurred recently. For example – in places where is bare soil after removal of shrubs and stump grinding (interlinking with other ongoing LIFE projects, e.g. WoodMeadowLIFE). Such soil is poor in nutrients, but rich with the natural seed material and soil microorganisms that promote wildflower seed germination. This will be accomplished without damaging EU habitat (a donor site);
  • In every HNV site, we will build specific ecological niches for invertebrates – insect hotels, old dead tree trunks, gravel piles, etc.;
  • In a suitable spot wetland will be created providing ecological niches for wildlife on one hand and solving the problem of natural water retention during extreme weather event preparedness measures on the other.
Campaigning for conservation (T.4.2)
  • Every year we will make the public event – “Meadow day”. At this event, we will invite lectors and organize workshops;
  • We will make active social media platform for our activities and make articles and broadcasts about wildlife in the city using the exisiting social media channels of Latvian Fund for Nature.
Accessibility to biodiversity (T.4.4)

For rising people awareness we will establish info stands about HNV grasslands, different life forms, management regimes, and so on.

Monitoring
  • We will start plant monitoring for the evaluation of changes in plant composition (in selected sites) (T.3.2). A pre-restoration status is identified, which will be a baseline to evaluate conservation success;
  • We will engage people in citizen science by asking them to report about wildlife in the city and the superintendence of HNV-sites and use this data for assessing the status of the meadows as well plan the follow-up restoration actions.

Everyone Can Help Increase Biodiversity In The City!

Mow less often and let your plants bloom!

Mowing low and preventing the wildflowers that are native to Latvia from flowering makes lawns species poor and impoverished;

Check if early mowing is necessary!

Early mowing is a way to limit the development of expansive species, but it is not necessary in all urban grassland areas! Expansive species such as ground-elder (Aegopodium podagraria), common dandelion (Taraxacum officinale), sickle Medick (Medicago falcata) and others outcompete the more desirable, slow-growing urban meadow plants such as cowslip (Primula veris), meadow Buttercup (Ranunculus acris), germander Speedwell (Veronica chamaedrys) and yellow rattle (Rhinanthus sp.). Without early mowing, the urban meadows would be overtaken by grasses by Midsummer, while the sown plants would be stressed and weakened. Observe how quickly the meadows regrow after the first mowing – usually, the meadow is blooming and lush again after just a month. However, early mowing is not necessary in open sunny areas with poor soil fertility, where vegetation does not develop as quickly. Such urban meadow areas are left unmown until most plants have finished blooming.

Collect wild plant seeds yourself to create an urban meadow or meadow plant island in your yard!

Tās var ievākt grāvmalās, ceļmalās, ūdeņu malās, mežmalās, kā arī vecās atmatās un ilgstoši nepārsētos ilggadīgos zālājos. Tāpat vari meklēt vietējas izcelsmes savvaļas augu sēklu maisījumus. Veikalos pieejamos importa sēklu maisījumus nevajadzētu izmantot vai arī izmantot tikai pavisam nelielās platībās un kontrolējamos apstākļos, jo tie var apdraudēt vietējo savvaļas augu sugu ģenētisko daudzveidību un saglabāšanos nākotnē.

Help collect wild plant seeds!

Join the initiative “Let’ s Make a Meadow Together!” and send us the wild plant seeds you have collected – we will sort them and sow them in the most suitable place! To join the volunteer seed collection movement, email us at ldf@ldf.lv or call 67830999.
