Human impacts on the Earth's ecosystems are now so pervasive that the UN has declared 2021-2030 the Decade of Ecosystem Restoration, building on the growing global acceptance that degraded ecosystems are not fully recovering and human-driven climate change has placed us in a `code red' state of emergency. Given that streams and river ecosystems serve as hotspots of biodiversity and human impacts, their condition is representative of their surrounding landscapes. As such, streams serve as model systems explore mechanisms behind restoration delay and success. Theoretically, the goal of restoration is to restore positive resistance and resilience mechanisms such that desired properties are self-perpetuating without ongoing interventions. However, recovery continues to show delays. My research has consistently shown that degraded streams remain resilient due to mismatched restoration actions that keep them in an unhealthy state. Taking a diverse and inclusive approach, progress towards a new framework - the Agricultural Stream Syndrome - will bring together the biotic and abiotic attributes of degradation to accelerate efforts to ensure full ecosystem recovery. To pivot the focus of restoration on accelerated ecosystem recovery, the long-term vision for this program is to develop a new paradigm for addressing degraded - and restoring - agricultural streams, herein called the Agricultural Stream Syndrome. This program will engage local and Indigenous knowledge systems alongside diverse research methodologies that include field surveys to capture riparian-instream and ecosystem function relationships, data syntheses to extract and confer trait-based community properties and assess the global restoration literature, and, to implement a space-for-time study approach in the field which will engage spatially distinct sites as proxies for long-term ecological time series. We will use this program as a step towards longer-term, larger scale stream restoration experiments on the ground, in real world contexts. In the coming five years, I will empower and train HQP to test the hypothesis that negative resistance and resilience mechanisms (sensu Barrett et al. 2021) underpin delayed ecosystem recovery. We will conduct field surveys on riparian plants and in-stream benthic macroinvertebrates to quantify cross-system relationships, apply functional trait data to confer these relationships and generate hypotheses on what restoration action(s) have the potential to ignite and sustain desired interactions. Working almost entirely on agricultural landscapes in the region, this program necessitates an equitable, diverse and inclusive approach to the research, engaging Settler and Indigenous knowledge systems, local communities, practitioners, government and industry all as research partners to achieve the short-term objectives and work towards the long-term vision.

现在，人类对地球生态系统的影响是如此普遍，联合国已宣布2021 - 2030年生态系统恢复的十年，建立在日益增长的全球认可的基础上，以至于退化的生态系统尚未完全恢复，人类驱动的气候变化使我们处于“紧急情况”状态。鉴于溪流和河流生态系统是生物多样性和人类影响的热点，因此它们的状况代表了周围的景观。因此，流充当模型系统探索恢复延迟和成功背后的机制。从理论上讲，恢复的目的是恢复积极的抵抗力和弹性机制，使所需的特性在不进行干预的情况下自我延续。但是，恢复继续显示延迟。我的研究一直表明，由于不匹配的恢复行动使它们处于不健康状态，因此退化的流源保持韧性。采用一种多样化和包容的方法，朝着新框架（农业流综合征）的进步将降级的生物和非生物属性汇集在一起​​，以加快努力，以确保完整的生态系统恢复。为了使恢复重点放在加速生态系统恢复上，该计划的长期愿景是开发一种新的范式来解决降级和恢复 - 农业流的范式，此处称为农业流综合征。该计划将与当地和土著知识系统一起与多样化的研究方法相同，其中包括现场调查，以捕获河岸启动和生态系统功能关系，数据合成以提取和赋予基于特质的社区属性并评估全球恢复文献，并评估全球恢复文献，并在现场实施空间不同的现场实时时间效率的研究方法，该方法将在空间上不同的地点进行经过长期的时间来源，以促进长期的生态学系列。在现实世界中，我们将使用该程序作为迈向地面上长期，更大的流恢复实验的一步。 在接下来的五年中，我将授权和训练HQP，以检验以下假设：负电阻和弹性机制（Sensu Barrett等，2021）是延迟生态系统恢复的基础。我们将对河岸植物和河流底栖大型无脊椎动物进行现场调查，以量化跨系统关系，应用功能性状数据来赋予这些关系，并在哪种恢复作用（S）具有点燃和维持期望相互作用的潜力上产生假设。该计划几乎完全在该地区的农业景观上工作，需要对研究，与定居者和土著知识系统，地方社区，从业人员，政府和工业成为研究合作伙伴的公平，多样化和包容性的方法，以实现短期目标并致力于长期愿景。
