Łomżyński Park Krajobrazowy Doliny Narwi (Lomza Landscape Park of the Narew Valley) protects a scenic stretch of the Narew River valley near the city of Łomża in the Podlaskie Voivodeship of northeastern Poland. Established on 10 December 1994, the park covers approximately 7,354 hectares encompassing the dramatic Narew River escarpment, riparian forests, wet meadows, and upland terrain above the valley. ^[1] The park preserves the natural character of this section of the Narew, where the river has carved a deep valley creating steep bluffs with panoramic views over the broad floodplain below. Around 200 bird species have been recorded, with 137 nesting species, including internationally significant populations of white stork, corncrake, and various wetland birds supported by the traditionally managed floodplain meadows. ^[1]

The park combination of river, floodplain meadows, and upland forests supports diverse wildlife characteristic of the Narew valley corridor. Around 200 bird species have been recorded in the park, of which 137 are nesting species. ^[1] White storks are abundant, with numerous nests in surrounding villages sustained by rich feeding in the wet meadows. Corncrakes breed in the traditionally managed floodplain grasslands. The river itself supports beaver colonies and 30 fish and lamprey species. Raptors including white-tailed eagles and common buzzards hunt over the valley mosaic. The park also supports 46 mammal species, 12 amphibian species, and 4 reptile species. ^[1] During migration, the broad valley bottom serves as a staging area for geese, cranes, and various waders.

The park encompasses distinct vegetation zones from the river edge to the upland plateau. Active channel margins support pioneer willow communities, grading into more established riparian forests of white willow and black poplar on the floodplain. The seasonally inundated meadows maintain species-rich grassland communities with sedges, rushes, and moisture-loving herbs, including 47 plant species under full or partial protection. ^[1] Above the flood level, dry grasslands on the sandy escarpment host different plant assemblages. The upland plateau supports mixed forests of pine and oak on sandy soils, with richer oak-hornbeam woodland on morainic deposits. The vegetation diversity reflects the dramatic topographic and hydrological gradient compressed within the park.

The park defining feature is the Narew valley escarpment, rising approximately 40 to 50 metres above the river where it has undercut the edge of the morainic plateau. ^[1] The escarpment exposes glacial deposits from the Vistulian ice age, including boulder clay, sands, and gravels. The broad valley floor below is filled with Holocene alluvial deposits continuously reworked by the river during flood events. Sandy river terraces at intermediate levels record former floodplain heights before the river incised to its current level. The morainic plateau above consists of undulating terrain with scattered kettle depressions and poorly drained hollows.

The park experiences a distinctly continental temperate climate characteristic of northeastern Poland. Mean annual temperature is approximately 7 degrees Celsius, with cold winters averaging minus 4 to minus 5 degrees Celsius in January and warm summers reaching 18 degrees Celsius in July. The continental character produces a large annual temperature range and reliable snow cover through winter months. Annual precipitation reaches 550 to 600 mm with a clear summer maximum associated with convective storms. The Narew valley acts as a cold air drainage channel, with temperature inversions common on calm nights. Spring flooding from snowmelt typically occurs in March to April, inundating the valley floor meadows.

The Narew escarpment has attracted settlement since prehistoric times due to its defensive position and the rich resources of the river valley below. The city of Łomża, founded in the medieval period on the escarpment edge, exploited this strategic advantage for centuries. The broad floodplain meadows have been managed for hay production since at least the medieval period, with the annual mowing regime maintaining the open grassland character that supports the park internationally significant bird populations. River transport on the Narew connected local communities with the broader Vistula system. The area position in the northeastern borderlands meant it experienced successive military campaigns, most devastatingly during World War I and II.

Łomżyński Park Krajobrazowy Doliny Narwi was established on 10 December 1994 by ordinance of the Łomża Voivode, to protect the scenic and natural values of the Narew escarpment and valley corridor near Łomża. ^[1] The park creation recognized the importance of maintaining traditional meadow management and protecting the river corridor from development encroachment. Earlier conservation efforts focused on specific nature reserves within the current park boundaries. The landscape park framework provided comprehensive protection for the entire escarpment-valley system, ensuring that the dramatic landscape visible from Łomża would be preserved against suburban expansion and that the ecologically vital floodplain meadows would continue to be managed sustainably. The park total protected area covers 19,596.8 hectares including a 12,228-hectare buffer zone.

The park offers scenic walks along the escarpment edge with panoramic views over the Narew valley and distant forest horizons. Viewpoints from the bluff provide perspective on the river meandering course and the patchwork of wet meadows below. Trails descend the escarpment to the valley floor for walks along the river bank and through floodplain meadows. The city of Łomża itself provides cultural attractions including historic churches and a regional museum. Cycling routes along the valley edge connect viewpoints and descend to riverside paths. Birdwatching is particularly rewarding during spring migration and the breeding season when the wet meadows are alive with wader and stork activity.

The park is directly accessible from Łomża, with the escarpment viewpoints reachable on foot from the city center. Łomża has rail and bus connections to Warsaw, Białystok, and other regional centers. Parking areas serve access points away from the urban area. Trail markings guide visitors along the escarpment and down into the valley. Accommodation and dining are available in Łomża. The escarpment walks are mostly easy, while valley-floor trails can be wet during flood periods. No entrance fees apply. The park integration with the urban edge makes it accessible for casual visits as well as planned excursions.

Conservation management focuses on maintaining the floodplain meadow ecosystem through traditional mowing and protecting the river natural dynamics. The wet meadows require continued management to prevent succession to reed and willow, with agri-environment payments supporting farmers who maintain traditional practices. ^[1] Escarpment protection prevents construction on the unstable slopes and preserves the viewline from Łomża across the valley. Water quality in the Narew is monitored for inputs from upstream sources. Urban expansion from Łomża toward the escarpment edge is managed through planning controls. The park serves as an important educational resource for the city population understanding of river ecology. The park total protected area, including its 12,228-hectare buffer zone, covers 19,596.8 hectares in total.
