WEBVTT 01 00:00:12.780 --> 00:00:16.900 Today we have here Anne Raunio, Tytti Kontula, and 2 00:00:16.900 --> 00:00:21.520 Ulla-Maija Liukko from the Finnish Environment Institute. 3 00:00:21.520 --> 00:00:26.420 We have an interesting question: who decides what 4 00:00:26.420 --> 00:00:34.420 is an "ecosystem"? This question relates to how when species’ threat status is assessed, 5 00:00:34.420 --> 00:00:38.800 the assessments are done on scientifically described taxa, 6 00:00:38.800 --> 00:00:42.120 typically species or subspecies, 7 00:00:42.120 --> 00:00:46.000 and defining a species is therefore pretty straightforward. 8 00:00:46.000 --> 00:00:52.060 But in ecosystems’ case the situation is a little different. 9 00:00:52.060 --> 00:00:57.390 The report of the Finnish ecosystems' threat assessment is quite a 10 00:00:57.390 --> 00:01:01.700 brick-like document, and more than half of the pages 11 00:01:01.700 --> 00:01:06.660 are dedicated to descriptions of the assessed ecosystems. 12 00:01:06.660 --> 00:01:12.810 Who wrote those descriptions and what are they based on? 13 00:01:12.810 --> 00:01:18.050 Well, the classification, or typology, of the ecosystems has been developed by the 14 00:01:18.050 --> 00:01:24.710 the same group of experts who then assesses the risk of collapse. 15 00:01:24.710 --> 00:01:29.770 So ultimately they, in a way, decide what those ecosystems are, but 16 00:01:29.770 --> 00:01:33.270 of course they have not done it alone. Many classifications of ecosystems, 17 00:01:33.270 --> 00:01:37.450 or ecosystem groups, rely heavily on 18 00:01:37.450 --> 00:01:41.540 Finnish knowledge on nature. For example, 19 00:01:41.540 --> 00:01:45.300 mire and peatland vegetation has been studied and categorized 20 00:01:45.300 --> 00:01:50.500 for decades, which of course affects the 21 00:01:50.500 --> 00:01:52.960 ecosystem classification in the threat assessment. 22 00:01:52.960 --> 00:01:57.280 But then, of course, there are also some ecosystem groups 23 00:01:57.280 --> 00:02:06.220 where assessors had to start the typification from scratch, such as rock outcrops. 24 00:02:06.220 --> 00:02:12.380 Anne, what can you tell us about the early days of ecosystem assessments? 25 00:02:12.380 --> 00:02:17.970 Did the work start from this kind of typification of ecosystems? 26 00:02:17.970 --> 00:02:23.230 Yes, it did, and also from outlining the assessment method, 27 00:02:23.230 --> 00:02:26.310 which, at that time, we constructed ourselves, nationally. 28 00:02:26.310 --> 00:02:31.140 But of course there is a huge amount of work behind the comprehensive typology 29 00:02:31.140 --> 00:02:33.090 of ecosystems that we have now. 30 00:02:33.090 --> 00:02:37.730 In Finland, we did not have a ready-made typology that would have covered all the 31 00:02:37.730 --> 00:02:43.710 ecosystem groups. There have been different classifications, mainly of forests and swamps, 32 00:02:43.710 --> 00:02:47.500 that were primarily based on the economic use of nature and its resources. 33 00:02:47.500 --> 00:02:49.300 But there were no 34 00:02:49.300 --> 00:02:52.290 overarching ecological classifications of nature. 35 00:02:52.290 --> 00:02:55.700 But, then [when making the typology] you have to take into account 36 00:02:55.700 --> 00:02:58.470 characteristics that are not ecological, as well. 37 00:02:58.470 --> 00:03:05.030 Specifically, there is the practical point of the kind of information and data needed in 38 00:03:05.030 --> 00:03:07.410 the threat assessments - and whether that is available 39 00:03:07.410 --> 00:03:13.230 for the selected units of assessment. Therefore, for example, typification of lakes 40 00:03:13.230 --> 00:03:19.130 went pretty much in the same line than in the EU Water Framework Directive, 41 00:03:19.130 --> 00:03:27.010 so in the future, data accumulates from directive reports also to red-listing. 42 00:03:27.010 --> 00:03:31.550 So, an assessment unit, or an ecosystem, is 43 00:03:31.550 --> 00:03:36.640 kind of a contractual thing, 44 00:03:36.640 --> 00:03:38.960 which has its pros and cons. 45 00:03:38.960 --> 00:03:45.160 Now that the IUCN wants to compile a global Red List of ecosystems, 46 00:03:45.160 --> 00:03:50.390 that work also starts with typifying or defining the ecosystems, so there 47 00:03:50.390 --> 00:03:57.290 is a global ecosystem typology under way. It remains 48 00:03:57.290 --> 00:03:59.880 to be seen, then, how the Finnish ecosystems fit into the global typology. 49 00:03:59.880 --> 00:04:07.370 The global typology has actually just 50 00:04:07.370 --> 00:04:10.940 been published, in Nature, 51 00:04:10.940 --> 00:04:21.120 just a week or two ago. - Oh, great, I must read the paper right away. 52 00:04:21.120 --> 00:04:28.280 OK, if we continue to think about the differences between assessing species and ecosystems, 53 00:04:28.280 --> 00:04:34.680 what kinds of differences are there in the practices of these assessments? For example, 54 00:04:34.680 --> 00:04:39.840 if you think about how the assessment proceeds? It was just pointed out that with ecosystems 55 00:04:39.840 --> 00:04:44.920 quite often the starting point is defining the units of assessment, that is, making the ecosystem 56 00:04:44.920 --> 00:04:48.000 definitions and descriptions into an ecosystem typology. 57 00:04:48.000 --> 00:04:53.040 With species, the scientifically described taxa are the starting point. 58 00:04:53.040 --> 00:04:58.030 So that is one clear difference. 59 00:04:58.030 --> 00:05:03.930 But if you think of the work as a project that begins at this starting point and ends 60 00:05:03.930 --> 00:05:08.640 in the publication of the Red List, which is the results document that is printed and put 61 00:05:08.640 --> 00:05:13.260 online for people to see, what happens in between the beginning and the end? 62 00:05:13.260 --> 00:05:19.960 Would you like to summarize the process of species threat assessment, Ulla-Maija? 63 00:05:19.960 --> 00:05:25.380 There is quite a lot going on there, too, at a higher administrative level, as well, 64 00:05:25.380 --> 00:05:30.060 so the project starts with preparation. 65 00:05:30.060 --> 00:05:34.200 After that, we organize ourselves into expert groups and train participants. 66 00:05:34.200 --> 00:05:37.260 Then there is the actual assessment phase, and then comes 67 00:05:37.260 --> 00:05:40.120 the summarization and reporting phase. 68 00:05:40.120 --> 00:05:44.120 And if we talk only about 69 00:05:44.120 --> 00:05:47.040 the actual assessment phase, then 70 00:05:47.040 --> 00:05:53.690 once the assessor teams have been organized and trained, and they have read all the guidelines, 71 00:05:53.690 --> 00:05:57.310 then they start the work by examining the previous assessment's species lists 72 00:05:57.310 --> 00:06:01.080 to see if they are up to date 73 00:06:01.080 --> 00:06:07.020 and decide how to delimit the species groups 74 00:06:07.020 --> 00:06:09.640 included in the assessment. By this I mean, 75 00:06:09.640 --> 00:06:14.100 there are species that are left unassessed [NE] or that are deemed not applicable [NA] 76 00:06:14.100 --> 00:06:18.000 for the threat assessment. Are the old species lists 77 00:06:18.000 --> 00:06:21.140 up to date, in that way: 78 00:06:21.140 --> 00:06:22.960 are there any new species that need to be added 79 00:06:22.960 --> 00:06:25.370 or have any taxonomic changes occurred within the species group. 80 00:06:25.370 --> 00:06:29.220 All these things happen in that initial phase. 81 00:06:29.220 --> 00:06:32.820 And there has been a general rule that when the species lists 82 00:06:32.820 --> 00:06:36.140 are ready, then the so-called NE species, that is, those excluded from the assessment, 83 00:06:36.140 --> 00:06:39.420 and the NA species, which are the ones ineligible for assessment, 84 00:06:39.420 --> 00:06:47.000 and the species that are obviously LC, those are all dealt with first. 85 00:06:47.000 --> 00:06:49.400 These are 86 00:06:49.400 --> 00:06:52.220 taken care of in the beginning 87 00:06:52.220 --> 00:06:55.080 and then we wll concentrate on the species 88 00:06:55.080 --> 00:06:59.400 that need to be investigated in more detail. For them we need to go through 89 00:06:59.400 --> 00:07:03.100 the Red List criteria, think about the result categories, and so on. 90 00:07:03.100 --> 00:07:07.750 This is done in the expert teams, 91 00:07:07.750 --> 00:07:12.400 that do the assessment work for their particular species group. 92 00:07:12.400 --> 00:07:15.940 The team, then, makes a summary of the results of their assessment 93 00:07:15.940 --> 00:07:20.340 to a national steering group. The results are reviewed by the steering group, and when 94 00:07:20.340 --> 00:07:26.360 they are approved of, the team, or a part of the team - 95 00:07:26.360 --> 00:07:30.180 that depends on how they have organized themselves – 96 00:07:30.180 --> 00:07:33.560 the experts summarize the results, 97 00:07:33.560 --> 00:07:37.900 they write an article, or whatever it is called, which will be published in the Red List book. 98 00:07:37.900 --> 00:07:43.300 After this, the book has an editorial board that writes the general parts and 99 00:07:43.300 --> 00:07:46.880 edits and submits the national Red List. 100 00:07:46.880 --> 00:07:49.320 And then, of course, 101 00:07:49.320 --> 00:07:53.140 in addition to the Red List book, there are all kinds of online services we provide, and publicity work 102 00:07:53.140 --> 00:07:58.900 to do. That is the overall process in a nutshell. 103 00:07:58.900 --> 00:08:06.920 Is the process as smooth with the ecosystems threat assessment? 104 00:08:06.920 --> 00:08:09.750 How would you describe that process, Anne? 105 00:08:09.750 --> 00:08:15.090 The basic principle of the process is similar, 106 00:08:15.090 --> 00:08:17.770 but maybe on the ecosystem side 107 00:08:17.770 --> 00:08:25.610 there is even more interpreting and handling of data and information sources. 108 00:08:25.610 --> 00:08:31.250 So, among other things, the experts need to think about how the ecosystems that are named 109 00:08:31.250 --> 00:08:36.750 differently in different data sources, correspond to each other, 110 00:08:36.750 --> 00:08:39.970 and make decisions about what data can be used and what cannot. 111 00:08:39.970 --> 00:08:41.770 And, indeed, oftentimes for ecosystems 112 00:08:41.770 --> 00:08:45.980 there quite rarely are any comprehensive and clear data available 113 00:08:45.980 --> 00:08:51.140 from which it would be possible to directly measure changes in quality and quantity. 114 00:08:51.140 --> 00:08:56.560 Geographic analysis and combining data is, therefore, 115 00:08:56.560 --> 00:09:01.960 often required, to better extract information on ecosystems. 116 00:09:01.960 --> 00:09:08.040 So, quite a lot of demanding work with spatial data and 117 00:09:08.040 --> 00:09:13.890 ecosystem occurrence modelling is required. 118 00:09:13.890 --> 00:09:17.210 And those methods require expertise. 119 00:09:17.210 --> 00:09:22.310 I mean, making the assessments is not easy, and in fact, when it comes to species, 120 00:09:22.310 --> 00:09:24.110 IUCN requires a certain level of training, 121 00:09:24.110 --> 00:09:28.770 a specific kind of assessor training, for the species’ threat assessments. 122 00:09:28.770 --> 00:09:34.090 I do not think that anything similar has been established for the ecosystems' assessors; 123 00:09:34.090 --> 00:09:38.930 there it is more of a case of relying on the Red List coordinators to ensure 124 00:09:38.930 --> 00:09:45.860 that the experts are up to date. Isn't that right? 125 00:09:45.860 --> 00:09:51.740 Or have you been planning on some kind of new method curriculum for us, Tytti? 126 00:09:51.740 --> 00:09:53.540 No, I have not. 127 00:09:53.540 --> 00:09:59.160 I haven't had time to think about such a thing. Usually our expert groups 128 00:09:59.160 --> 00:10:02.350 are organized in such a way that 129 00:10:02.350 --> 00:10:09.800 there is a key person, a secretary, who then is under 130 00:10:09.800 --> 00:10:16.540 very close supervision, I could say, or belongs to a very close-knit project team, 131 00:10:16.540 --> 00:10:23.270 that has adopted the Red List criteria so well that we can be confident that 132 00:10:23.270 --> 00:10:29.390 the assessment truly does go by the book. 133 00:10:29.390 --> 00:10:33.920 Maybe in the next assessment we will have to give Tytti 134 00:10:33.920 --> 00:10:39.470 the title of assessor, to add even more weight to the assessment, 135 00:10:39.470 --> 00:10:43.830 to show that she determines how things are done. 136 00:10:43.830 --> 00:10:47.760 "Assessor" sounds great. 137 00:10:47.760 --> 00:10:52.200 Yeah, it has not been quite so strict 138 00:10:52.200 --> 00:10:58.570 with species, either. Assessing species on national level has been done 139 00:10:58.570 --> 00:11:04.370 without IUCN-educated assessors. There is the steering group, which 140 00:11:04.370 --> 00:11:09.010 has been established for, among other things, going through the assessments with the 141 00:11:09.010 --> 00:11:13.790 expert teams and ensuring that they have been conducted the work 142 00:11:13.790 --> 00:11:16.650 according to the Red List criteria and that different 143 00:11:16.650 --> 00:11:20.480 interpretations of the classifications 144 00:11:20.480 --> 00:11:23.600 correspond to each other. 145 00:11:23.600 --> 00:11:30.060 In fact, the IUCN assessor training is actually directed to 146 00:11:30.060 --> 00:11:33.720 those who are doing the global species assessments.
