In terms of quality, they were no different to all those American golf courses that have an international reputation for being maintained with far more pesticides, fertilizers and water than is necessary for a sustainable standard. Listening to <strong>Frank Rossi, Associate Professor in the Department of Agriculture and Life Sciences<\/strong>, however, gives you a different perspective on the top course. The famous golf course on Long Island has a second, less visible role: it is part of <g id=\"gid_2\">Bethpage State Park<\/g> and is therefore subject to a strict protection regime. The course is emblematic of the question of how top-class golf and nature conservation can be reconciled in a national park.    <\/p>\n<p>Cornell University, which has a 25-year partnership with the <strong>New York State National Park Service<\/strong> covering a total of 23 golf courses, plays a key role in this. Under <g id=\"gid_1\">Rossi&#8217;<\/g> s leadership, the university has been supporting greenkeeping for many years &#8211; in close coordination with the park&#8217;s managers. Rossi explained the approach to the university magazine <em>Cornell Chronicle <\/em>in the run-up to the Ryder Cup, focusing on the introduction of so-called Integrated Pest Management, in which the promotion of healthy grass areas should lead to a reduction in the use of pesticides. &#8220;It was our shared belief that this is our responsibility to the citizens of New York State and its residents.&#8221;<\/p>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-mg7svrba-dfdf26a2e250e253636cdcffbf2e72b5\">\n.avia-image-container.av-mg7svrba-dfdf26a2e250e253636cdcffbf2e72b5 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-mg7svrba-dfdf26a2e250e253636cdcffbf2e72b5 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-mg7svrba-dfdf26a2e250e253636cdcffbf2e72b5 av-styling- avia-align-center  avia-builder-el-4  el_after_av_textblock  el_before_av_image  av-has-copyright av-copyright-always'  ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-31616 avia-img-lazy-loading-not-31616 avia_image ' src=\"https:\/\/golfsustainable.com\/wp-content\/uploads\/2025\/09\/DSC04547-klein-1500x630.jpg\" alt='Andrew Wilson, Frank Rossi and Michael Hadley' title='Bethpage Black and Cornell University'  height=\"630\" width=\"1500\"  \/><\/div><small class=\"avia-copyright\">Andrew Wilson, Director of Agronomy, Frank Rossi, Associate Professor at Cornell University, and Michael Hadley, Superintendent of the Black Course (Image: Jake Zajkowski, Cornell Turfgrass Program)<\/small><\/div><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-mg1rcowo-7fd6b70d4587849088847efd0acbcd23\">\n.avia-image-container.av-mg1rcowo-7fd6b70d4587849088847efd0acbcd23 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-mg1rcowo-7fd6b70d4587849088847efd0acbcd23 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-mg1rcowo-7fd6b70d4587849088847efd0acbcd23 av-styling- avia-align-center  avia-builder-el-5  el_after_av_image  el_before_av_textblock '  ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-31605 avia-img-lazy-loading-not-31605 avia_image ' src=\"https:\/\/golfsustainable.com\/wp-content\/uploads\/2025\/09\/Bethpage-Black-2025-3-BM-Detail-1500x430.jpg\" alt='Bunker with rough' title='Bethpage Black 2025 Bunker'  height=\"430\" width=\"1500\"  \/><\/div><\/div><\/div>\n<section  class='av_textblock_section av-mg1re2kx-09b30c91f5ef02d3710cd602c583ee24 '  ><div class='avia_textblock' ><p>This can only be achieved through cooperation. Together, the university, club and park administration develop strategies that meet both sporting demands and ecological requirements. This includes consistent monitoring: weather data, soil analyses and vegetation maps provide the basis for making maintenance decisions on a daily basis. &#8220;By working with Cornell, we have all become more aware and cautious when it comes to applications and using the right product to protect the environment as a whole,&#8221; says <strong>Mike Hedley, Superintendent of the Black Course <\/strong>, summing up the cooperation.   <\/p>\n<div hcb-fetch-image-from=\"https:\/\/golfsustainable.com\/studie-parkinson-golf-konsequenzen-fuer-den-us-golfsport\/\" class='avia-iframe-wrap'>\n<blockquote class=\"wp-embedded-content\" data-secret=\"Fx5fkQQbH6\">\n<p><a href=\"https:\/\/golfsustainable.com\/en\/study-parkinsons-and-golf-us\/\">Studie Parkinson &#038; Golf: Konsequenzen f\u00fcr den US-Golfsport?<\/a><\/p>\n<\/blockquote>\n<p><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"&#8220;Studie Parkinson &#038; Golf: Konsequenzen f\u00fcr den US-Golfsport?&#8221; &#8212; Golf Sustainable\" src=\"https:\/\/golfsustainable.com\/en\/study-parkinsons-and-golf-us\/embed\/#?secret=kX5Ciopmq6#?secret=Fx5fkQQbH6\" data-secret=\"Fx5fkQQbH6\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/div>\n<p><strong>Reduction in pesticides<\/strong><br \/>\nThe reduction of pesticides was at the heart of the project right from the start. The reason for this was a regulation issued by New York State in 2000, in which the use of chemical pesticides was reduced. Long Island followed this regulation. Between 2001 and 2009, the use of chemical pesticides was reduced by 45 percent and the amount of fertilizer by 60 percent. The program was started on the Green Course and from there expanded to all courses in the New York National Park area. &#8220;We tested it scientifically and at the same time applied it immediately under championship conditions,&#8221; Rossi summarizes to the <em>Cornell Chronicle<\/em>.<\/p>\n<\/div><\/section>\n<section  class='av_textblock_section av-kt49pn-9571b5c3168ab4c0a6dc3161fb6a7dde '  ><div class='avia_textblock' ><p>INSERT_STEADY_NEWSLETTER_SIGNUP_HERE<\/p>\n<\/div><\/section>\n<section  class='av_textblock_section av-mg1rj04z-83259a85874f63b53224c7bb7d0b603b '  ><div class='avia_textblock' ><p><strong>Promoting biodiversity<\/strong><br \/>\nAt the same time, areas of the park are being specifically enhanced ecologically: The measures are part of an overall concept that the park management is monitoring and supporting. In particular, the strong establishment of native grass species, which can be seen on the edges of the bunkers facing away from the play area, play an important role in this. These were selected by <strong>plant expert Victor Azzaretto<\/strong>.  <\/p>\n<p><strong>Model character for the US golf world<\/strong><br \/>\nThe cooperation between Cornell University, the golf club and the National Park Service creates a model that points far beyond New York to the American market. During the Ryder Cup, scientists and park administrators will also have the opportunity to communicate their successful model more effectively. According to Rossi, the message is simple. Top quality and sustainable maintenance are not mutually exclusive.   <\/p>\n<div hcb-fetch-image-from=\"https:\/\/golfsustainable.com\/die-zuechtung-von-gras-ist-viel-komplexer-geworden\/\"
