Breeding Birds as a Farm Product

摘要: : Since the 1950s, meadowbird populations have been under increasing threat from radical changes in farming practices. We studied possibilities for conserving meadowbirds on modern, intensive dairy farms Netherlands. Here, conventional strategy conservation of is to restrict intensity and compensate farmers their production losses. To increase breeding success meadowbirds, however, can fine-tune practices yearly local circumstances. Because this fine-tuning difficult enforce by legislation, we propose that be paid clutches bred land. Thus, are what they produce, but not restricted The results first small-scale experiments, which was compared between where were paid, encouraging. Breeding significantly higher than ( breeding Lapwing [  Vanellus vanellus]: 64.7% farms, 48.2% unpaid farms; Black-tailed Godwit [  Limosa limosa]: 63.1% 39.3% unpaid). effects could yet detected. per-clutch payment system less expensive compensation income losses: paying costs 40 Euro per clutch, whereas compensating losses 100–400 clutch (1 approximately equal 1 U.S. dollar). Farmers enthusiastic, encourages cooperation nature conservationists. Resumen: Desde 1950, las poblaciones de aves pradera han estado amenazadas por cambios radicales en practicas agricolas. Estudiamos posibilidades conservar granjas lecheras modernas e intensivas Holanda. Aqui, la estrategia convencional para conservacion consiste restringir intensidad productiva y compensar perdidas a los granjeros. Sin embargo, incrementar el exito reproductivo granjeros pueden ajustar sus actividades productivas circunstancias anuales locales. Debido que es dificil ajustes sean observancia forzosa proponemos se pague numero nidadas producidas terrenos. Asi, les paga lo producen no restringen productivas. Los resultados estos experimentos pequena escala, fue estudiado cuyos duenos pagaron comparacion con sin pago, son alentadores. El significativamente mayor recibieron pago donde hubo (exito Vanellus vanellus pagadas, pago; Limosa limosa pago). No pudieron detectar efectos sobre pradera. sistema menos costoso basada compensacion produccion. tiene un costo nidada, mientras 100 – 400 nidada equivale aproximadamente dolar U.S.). estan entusiasmados promueve cooperacion entre conservacionistas.
