The nature reserve “Plieņciema kāpa” is founded in 1987 and covers 60.6 hectares of land. Since 2005 it is a Natura2000 site. The nature reserve protects a 150-200m wide and 3.5km long part of a distinct, continuous dune rampart. The dunes shelter Plieņciems village protecting from sea winds. The key natural values here are rare and protected biotopes of national and European significance: “Wooded dunes of the coast 2180” in the area of 61.8 ha, “Fixed dunes with herbaceous vegetation, 2130 (grey dunes)” in the area of 8.27 ha, “Shifting dunes along the shoreline with Ammophila arenaria (white dunes) 2120 in the area of 3.20 ha”, “Black alder swamp forests 9080”, ) in the area of 2,68 ha, as well as rare and protected species of Latvian and European significance including eastern pasqueflower (pulsatilla patens), Rolling Hen-and-chicks(Jovibarba sobolifera), Nothorhina muricata, Wryneck (Jynx torquilla), Woodlark (Lullula arborea).

In the nature reserve, there is a “Vabu square” – a deflation in the dune where for centuries local fishermen have been drying nets. In the 18^th and 19^th centuries ships were built here. Nine ships have been built here in 1882 - 1925. The four-masted gaff-rigged schooner with hoisting engine “Eurasia” was completed in 1925, the largest ship built by the Kurzeme fishermen. It was one of the works of Martin Morgenstern (1866-1945), a famous shipbuilding master.

Thanks to dunes, Plieņciems village was a popular holiday resort and has been mentioned in written sources already in 1738. Clergymen and landlords with their families used to stay here. In 1808, a merchant from Riga bought the local pub and replaced it with a massive two-storey building with a large ball-room and dining hall. On July 15, 1810, a sea bathing facility was opened for health treatment. For arrival of the empress Elisabeth Alexeievna, the wife of emperor Alexander I of Russia, who was a grandson of Catherine the Great, the road from Tukums town was repaired, the two highest hills were levelled, a road passage was dug across the Plieņciems dune, and a lime-tree alley was planted to facilitate access to the beach and bathing spot. Later, in 1920ies, the resort circles consisted mainly of the Kurzeme region landlords. There was a dance-floor in the park of Plieņciems village, and a special orchestra played music for resort guests three times a day.

 Место, где можно отправиться на короткие и продолжительные прогулки. Здесь создана «Тропа Спридитиса» (с деревянными скульптурами героев сказки Анны Бригадере), протяженностью 1,6 км, «Учебная тропа лесных пейзажей», протяженностью 3,8 км и 8-ми км (в одном направлении) «Тропа пейзажей Аугшземе». Тропы расположены в субгляциальной ложбине, сформировавшейся от таяния ледника, где друг за другом разместились соединенные протоками несколько озерков и болотцев. В целях охраны пейзажей и других ценностей создан природный заповедник. В начале троп (недалеко от Пилскалне) стоит 30-метровый Мелнайскалнс (городище Рамава).

This territory protects the shore of the onetime Baltic lake of ice, which most significant part stretches for 10 kilometres on the eastern side of the Grobiņa-Ventspils highway from Kapsēde till Vērgale bus stop. From the top of this ancient shoreline there is a lovely view of the Piejūra lowlands, but no specific viewing areas or information stands have been installed. There are protected species and habitats in the territory.

This is a mostly forested territory which is home to one of the largest areas of the white mistletoe, which is a semi-parasitic plant. It is best to observe this unique plant when it has no leaves. Latvia is the northern limit to the white mistletoe, which is why it is not all that common. It is interesting that even more of this rare specie can be seen outside of the nature restricted area.

Vairākas salas Zvirgzdenes ezerā, uz kurām saglabājušies platlapju (ozolu, liepu) meži ar bagātīgu zemsedzes floru. Salas var redzēt no ceļiem, kas piekļaujas ezera ziemeļu un austrumu krastam.

The Grey Dune of Pāvilosta nature reserve covers 42 hectares of land and has been designated to protect Latvia’s widest dune (1.5 km parallel the seacoast, and 812m in the direction from the sea to inland) and the biotopes and species found there. A two-storied watching platform is built to savour the scenery.

 In Soviet time, local fishermen used to dry seaweed in dunes for production of agar, and thus rich vegetation developed in the dune. The Gray Dune is part of a unique landscape with the sea view, the traditional architecture of Pāvilosta fishing town, and biotopes, including protected, which border the nature reserve: pine forest, embryonic dunes, white dunes, and wet beech where once can find springs. Biotope 2130, “Fixed dunes with herbaceous vegetation (grey dunes)” is found here. At present, pines are taking over the biotope, therefore some maintenance activities are required. The Grey Dune is most beautiful in the second half of July and in August when the blossoming Breckland Thyme (Thymus serpyllum) and Narrowleaf Hawkweed (Hieracium umbellatum) colour the dune in shades of yellow and violet. The most typical species here are Pasqueflower (Pulsatilla pretense), Grey Hair-grass(Corynephorus canescens), Blue Hair Grass (Koeleria glauca), Sand Pink (Dianthus arenarius).

The Gray Dune earned wide recognition when a group of enthusiasts actively campaigned for six years to achieve the status of the nature reserve. Guna Grimsta, a group representative remembers that they organised events and activities throughout Latvia involving large part of the society, prominent personalities, church parishes, NGOs, school youth and university students. The activists were writing letters, making videos, doing research articles, composing music, collecting signatures and submitting proposals to achieve official status of the Grey Dune as an especially protected nature site. They organised seminars, concerts, art plenaires and exhibitions, educational excursions, joint-work, musical church services, meetings with high officials and their on-site visits to the Gray Dune.

In 2006 the group received the title „Proudness of Latvia” awarded by the national TV3 broadcasting company and daily paper „Diena”.
The nature reserve „Gray Dune of Pāvilosta” was established in October 30, 2007. It is the most recent Natura2000 site in Latvia.

This swampy territory used to be part of a Littorena Sea lagoon, and it is a place where many rare and protected birds such as woodpeckers live and nest. Territory is hard to reach although some of the territory can be surveyed from the Tukums-Kolka road. Wet meadows is called "lankas" in Kurzeme region.
