BIODIVERSIDAD SOBRE CUBIERTAS VERDES

A partir de 2016, había 60 acres de techos verdes en la ciudad de Nueva York. Los techos verdes se encuentran en edificios residenciales, comerciales, urbanos, estatales e institucionales, incluidas universidades e instalaciones importantes como el Centro de Convenciones Jacob K. Javits. Si bien esto puede parecer mucho, los techos verdes representan menos de una décima parte del porcentaje de aproximadamente 1 millón de techos de la ciudad, que son aproximadamente 40,000 acres de espacio subutilizado.

Pájaros en tejados verdes

Las aves usan la ciudad de Nueva York en todas las estaciones del año. Algunas aves se reproducen en Nueva York, algunas pasan el invierno aquí y otras pasan por la migración de primavera u otoño. En muchas partes de Nueva York, las aves no tienen acceso a suficientes espacios verdes para encontrar la comida y el refugio que necesitan. Los techos verdes pueden proporcionar un hábitat en áreas donde las aves no podrían sobrevivir de otra manera.

Se han registrado más de 48 especies de aves utilizando techos verdes en Nueva York. La mayoría usa techos verdes durante la migración de primavera y otoño . Durante la migración, las aves viajan largas distancias, pero necesitan repostar de vez en cuando. Los techos verdes actúan como sitios de parada, donde las aves se alimentan de la abundante comunidad de insectos que se encuentran allí.

  • What is the DEP Green Infrastructure Grant?
    The Green Infrastructure Grant has helped fund over 30 green roofs since its inception in 2011. This grant program, funded by the New York City Department of Environmental Protection (DEP), is an incentive for private property owners to retrofit their NYC rooftops with green roofs.
  • What are the Green Infrastructure Grant eligibility requirements?
    As of 2019, a green roof retrofit must be 3,500 square feet, have a minimum of 1.5 inch soil depth, and manage at least 1 inch of rainfall. Visit the DEP’s website for the most up-to-date eligibility requirements.
  • What will the grant cover?
    Funding is for the design and construction of green roof retrofits on private property. The amount is determined by the green roof area (GRA) and soil depth. The grant will reimburse $10 to $30 per square foot for an eligible green roof.
  • What are the steps to submit an application?
    Private property owners within New York City's five boroughs are encouraged to apply for the Green Infrastructure Grant. Prior to submitting an application, schedule a preliminary meeting with a DEP representative to ensure the project is viable and to discuss timelines. Be prepared to review the structural integrity of the roof, the project size, and which sewer drainage area the building is in, as these are essential for the project to move forward.
  • What else should I know before considering an application?
    Property owners must execute a funding agreement with the DEP. Included in the funding agreement is a Declaration of Restrictive Covenant, which requires the property owner to commit to maintaining the green roof for at least 20 years. The funding agreement and the Declaration are available on the DEP’s website and should be reviewed by the property owner and their legal counsel prior to submitting an application.

Murciélagos en tejados verdes

Los murciélagos son un componente importante de los ecosistemas y ayudan a proteger a las personas al mantener bajo control las poblaciones de insectos plaga. En América del Norte, muchas especies de murciélagos están en peligro debido al síndrome de la nariz blanca o la pérdida de hábitat. Los techos verdes proporcionan un hábitat para los murciélagos en la ciudad.

Plants on Green Roofs

Artrópodos en tejados verdes

Los artrópodos son invertebrados con exoesqueletos, que incluyen abejas, insectos verdaderos, arañas y hormigas. Los artrópodos proporcionan alimento para otros animales salvajes, polinizan plantas, controlan las especies de plagas, descomponen el material vegetal y ciclan el suelo.

El área que rodea un techo verde y la conectividad de un techo verde influyen en los artrópodos que se encuentran, al igual que el diseño del techo verde . Los techos verdes en Nueva York albergan una mayor riqueza y abundancia de artrópodos que los techos convencionales no verdes y pueden desempeñar un papel importante en el aumento de la diversidad de artrópodos en toda la ciudad.

Plantas en tejados verdes

La diversidad de plantas en los techos verdes está determinada por la profundidad del medio de cultivo. En Nueva York, se sabe que varias especies de plantas nativas sobreviven en techos verdes de diferentes profundidades , y los investigadores están probando más. Además de lo que se planta intencionalmente, nuevas especies de plantas colonizarán los techos verdes, aumentando la diversidad de plantas.

La introducción de plantas en una superficie de techo previamente impermeable crea un hábitat para microbios, hongos, artrópodos, pájaros y murciélagos. En los sitios a nivel del suelo, las plantas nativas proporcionan un mejor hábitat para la vida silvestre nativa y es probable que lo mismo sea cierto para los techos verdes. Sin embargo, se necesita más investigación sobre qué plantas nativas pueden sobrevivir en techos verdes en Nueva York.

Microbios en tejados verdes

Varios grupos de microbios, incluidos los hongos micorrízicos, los hongos descomponedores, las bacterias fijadoras de N y los patógenos, son importantes para el funcionamiento de los ecosistemas no construidos y probablemente tengan implicaciones para el diseño y el mantenimiento de los techos verdes. Estos grupos funcionales interactúan con ciertos taxones de plantas y propiedades del suelo de formas complejas. Las comunidades de bacterias y hongos son diferentes en los techos verdes con vegetación mixta (flores silvestres, pastos y suculentas) que en los techos verdes de un solo género (Sedum). Hay una mayor proporción de hongos micorrízicos en los techos de vegetación mixta. Los techos de Sedum tienen una mayor carga de patógenos.

Las comunidades de hongos de los techos verdes tienen una composición distinta a la de los parques de la ciudad, y solo el 54 por ciento de los taxones microbianos de los techos verdes se encontraron en los suelos de los parques. A lo largo de los techos verdes de la ciudad, las comunidades de hongos están agrupadas geográficamente, lo que indica que los factores locales como las variaciones edáficas, los patrones de viento y la dispersión de los parques cercanos pueden haber dado forma a los conjuntos de hongos .
