2021年,百万植树计划宁夏项目继续与灵武市白芨滩防沙林场合作，共得到20家林地赞助商的支持，在白芨滩保护区内总计治沙一千亩，栽植各类灌木共二十万余株。
Supported by 20 forest sponsors, the Million Tree Project continued its desert control efforts in cooperation with Baijitan Tree Farm in 2021. Another 200,000 shrubs have been planted, covering a total area of 66.67 hectares in Baijitan Nature Reserve.

根据当地气候、水文情况。项目将采用灌木种植搭配草方格固沙的模式进行治沙以及生态恢复工作。每块沙地一般会需要4轮种植来确保造林效果，以确保灌木树种的亩栽植量不低于180株/亩。
According to local climate condition and hydrologic regime, we choose to plant a mix of shrubs and grass on the straw girds constructed to control sand movements. In every forest site, we need to plant four times to make sure at least 180 shrubs survived per Mu.
第一轮种植已于2021年11月30日前完成，即完成了所有的草方格固沙，并在雨季完成了柠条、花棒的种籽点播。每亩点播在200到300格草方格之间，即每2×1格会播种一次，同时会配合1kg沙蒿的草籽的撒播。据统计当地每名工作人员每日可以完成约300平方米（半亩）沙地的草方格制作和种植工作，所以完成这轮工作需要40名工作人员约50日的工作时间。
We have finished the construction of straw grids before the end of November, and sown seeds of Caragana Korshinskii Kom and Hedysarum scoparium in the straw grids during the raining season. The planting density is two meters by one meter, which means 200 to 300 grids per Mu have been sown seeds in. In addition, 1kg Artemisia ordosica seeds have been broadcasted per Mu. One worker can do about 300 squares per day. It took approximately 50 days for 40 works to finish the work.

由于新冠疫情的原因, 2021年宁夏志愿者植树活动不得不取消，活动名额保留至来年下一次活动使用。为遵循防疫要求，生态调查也中止对外招募志愿者。今年生态调查从9月27日开始到10月1日结束， 由根与芽员工完成，期间调查各年份林地灌木生长情况、林地覆盖度和生物多样性。
According to response by the COVID-19 Preventionand Control Office in Lingwu, we had to cancel the Ningxia planting trips. The trip spots will be reserved for the trips planned in 2022. The forest survey volunteer recruitment was stopped as well, so four MTP staff and intern together completed the survey during September 27 to October 1. The forest survey investigated the growth status of shrubs, the vegetation coverage and biodiversity of the five forest sites planted between 2015 to 2020.
